This patchset adds early fb blank feature that a callback of lcd panel
driver is called prior to specific fb driver's one. In the case of
MIPI-DSI based video mode LCD Panel, for lcd power off, the power off
commands should be transferred to lcd panel with display and mipi-dsi
controller enabled because the commands is set to lcd panel at vsync porch
period. and in opposite case, the callback of fb driver should be called
prior to lcd panel driver's one because of same issue. Also if fb_blank
mode is changed to FB_BLANK_POWERDOWN then display controller would be
off(clock disable) but lcd panel would be still on. at this time, you
could see some issue like sparkling on lcd panel because video clock to be
delivered to ldi module of lcd panel was disabled. this issue could
occurs for all lcd panels.
The callback order is as the following:
at fb_blank function of fbmem.c
-> fb_notifier_call_chain(FB_EARLY_EVENT_BLANK)
-> lcd panel driver's early_set_power()
-> info->fbops->fb_blank()
-> spcefic fb driver's fb_blank()
-> fb_notifier_call_chain(FB_EVENT_BLANK)
-> lcd panel driver's set_power()
-> fb_notifier_call_chain(FB_R_EARLY_EVENT_BLANK) if
info->fops->fb_blank() was failed.
fb_notifier_call_chain(FB_R_EARLY_EVENT_BLANK) would be called to revert
the effects of previous FB_EARLY_EVENT_BLANK call. and note that if
early_set_power() of lcd_ops is NULL then early fb blank callback would be
ignored.
This patch:
Add early_set_power and r_early_set_power callbacks. early_set_power
callback is called prior to fb_blank() of fbmem.c and r_early_set_power
callback is called if fb_blank() was failed to revert the effects of the
early_set_power call of lcd panel driver.

spi_driver_register() so we can drop the manual assignment.
The patch was generated using the following coccinelle semantic patch:

This patch fixes the cleanup code of the bfin_adv7393_fb_probe
function.
1) The resources were not freed in the order that we allocated them
so we call dma_free_coherent() before it was allocated.
2) The labels weren't in the right place which also meant that we
freed resources that weren't allocated.
3) We should free gpio_free(P_IDENT(P_PPI0_FS3)) before returning.
4) Lets change the label names into something more meaningful.

Lots of normal development commits, but perhaps most notable changes are:
* HDMI rework to properly decouple the HDMI audio part from the HDMI video part.
* Restructure omapdss core driver so that it's possible to implement device
tree support. This included changing how platform data is passed to the
drivers, changing display device registration and improving the panel driver's
ability to configure the underlying video output interface.
* Basic support for DSI packet interleaving

The new clock subsystem was merged in linux-3.4 without any users, this
now moves the first three platforms over to it: imx, mxs and spear.
The series also contains the changes for the clock subsystem itself,

these changes, in order to avoid interdependencies and conflicts.

"This is the main merge window request for the drm.
It's big, but jam packed will lots of features and of course 0
regressions. (okay maybe there'll be one).
Highlights:
- new KMS drivers for server GPU chipsets: ast, mgag200 and cirrus
(qemu only). These drivers use the generic modesetting drivers.
- initial prime/dma-buf support for i915, nouveau, radeon, udl and
exynos
- switcheroo audio support: so GPUs with HDMI can turn off the sound
driver without crashing stuff.
- There are some patches drifting outside drivers/gpu into x86 and
EFI for better handling of multiple video adapters in Apple Macs,
they've got correct acks except one trivial fixup.
- Core:
edid parser has better DMT and reduced blanking support,
crtc properties,
plane properties,
- Drivers:
exynos: add 2D core accel support, prime support, hdmi features
intel: more Haswell support, initial Valleyview support, more
hdmi infoframe fixes, update MAINTAINERS for Daniel, lots of
cleanups and fixes
radeon: more HDMI audio support, improved GPU lockup recovery
support, remove nested mutexes, less memory copying on PCIE, fix
bus master enable race (kexec), improved fence handling
gma500: cleanups, 1080p support, acpi fixes
nouveau: better nva3 memory reclocking, kepler accel (needs
external firmware rip), async buffer moves on nv84+ hw.
I've some more dma-buf patches that rely on the dma-buf merge for vmap
stuff, and I've a few fixes building up, but I'd decided I'd better
get rid of the main pull sooner rather than later, so the audio guys
are also unblocked."

Here is the big USB 3.5-rc1 pull request for the 3.5-rc1 merge window.
It's touches a lot of different parts of the kernel, all USB drivers,
due to some API cleanups (getting rid of the ancient err() macro) and
some changes that are needed for USB 3.0 power management updates.
There are also lots of new drivers, pimarily gadget, but others as well.
We deleted a staging driver, which was nice, and finally dropped the
obsolete usbfs code, which will make Al happy to never have to touch
that again.
There were some build errors in the tree that linux-next found a few
days ago, but those were fixed by the most recent changes (all were due
to us not building with CONFIG_PM disabled.)

"Here is the big USB 3.5-rc1 pull request for the 3.5-rc1 merge window.
It's touches a lot of different parts of the kernel, all USB drivers,
due to some API cleanups (getting rid of the ancient err() macro) and
some changes that are needed for USB 3.0 power management updates.
There are also lots of new drivers, pimarily gadget, but others as
well. We deleted a staging driver, which was nice, and finally
dropped the obsolete usbfs code, which will make Al happy to never
have to touch that again.
There were some build errors in the tree that linux-next found a few
days ago, but those were fixed by the most recent changes (all were
due to us not building with CONFIG_PM disabled.)

them from distracting in the diffstat in the other series.
A significant number of lines get removed here, in particular because
the ixp2000 and ixp23xx platforms get removed. These have never been
extremely popular and have fallen into disuse over time with no active
maintainer taking care of them. The u5500 soc never made it into a

Many good cleanups also went into the at91 and omap platforms, as has
been the case for a number of releases.

The VENC interfaces uses it's venc_set_timing() function to take in a new set
of timings. If the panel is disabled, it does not disable and re-enable the
interface. Currently, the manager timings are applied in venc_power_on(), these
are not called by set_timings if the panel is disabled. When checking overlay
and manager data, the DSS driver uses the last applied manager timings, and not
the timings held by omap_dss_device struct. Hence, there is a need to apply the
new manager timings even if the panel is disabled.
Apply the manager timings if the VENC panel is disabled.
This is similar to the commit below which fixed the same issue for HDMI/DPI

DSS2 driver uses the timings in manager's private data to check the validity of
overlay and manager infos written by the user. For VENC interface, we divide the
Y resolution by half when writing to the DISPC_DIGIT_SIZE register as the
content is interlaced. However, the height of the manager/display with respect
to the content shown through VENC still remains the same.
The VENC driver divides the y_res parameter in omap_video_timings by half, and
then applies the configuration. This leads to manager's private data storing
the wrong Y resolution. Hence, overlay related checks fail.
Ensure that manager's private data stores the original timings, and the Y
resolution is halved only when we write to the DISPC register. This is a hack,
the proper solution would be to pass some sort of interlace parameter which
makes the call whether we should divide y_res or not.

TILER is a block in OMAP4's DMM which lets DSS fetch frames in a rotated manner.
Physical memory can be mapped to a portion of OMAP's system address space called
TILER address space. The TILER address space is split into 8 views. Each view
represents a rotated or mirrored form of the mapped physical memory. When a
DISPC overlay's base address is programmed to one of these views, the TILER
fetches the pixels according to the orientation of the view. A view is further
split into 4 containers, each container holds elements of a particular size.
Rotation can be achieved at the granularity of elements in the container. For
more information on TILER, refer to the Memory Subsytem section in OMAP4 TRM.
Rotation type TILER has been added which is used to exploit the capabilities of
these 8 views for performing various rotations.
When fetching from addresses mapped to TILER space, the DISPC DMA can fetch
pixels in either 1D or 2D bursts. The fetch depends on which TILER container we
are accessing. Accessing 8, 16 and 32 bit sized containers requires 2D bursts,
and page mode sized containers require 1D bursts.
The DSS2 user is expected to provide the Tiler address of the view that it is
interested in. This is passed to the paddr and p_uv_addr parameters in
omap_overlay_info. It is also expected to provide the stride value based on the
view's orientation and container type, this should be passed to the screen_width
parameter of omap_overlay_info. In calc_tiler_rotation_offset screen_width is
used to calculate the required row_inc for DISPC. x_predecim and y_predecim are
also used to calculate row_inc and pix_inc thereby adding predecimation support
for TILER.

Commit 05dd0f5308 ("OMAPDSS: DISPC: Update
Accumulator configuration for chroma plane") adds
dispc_ovl_set_accu_uv() function that sets the accu, but the function
only handles YUV and NV12 modes, and BUGs otherwise.
The patch also adds a call to the function, but unfortunately the place
of call was such that the mode could be other than YUV or NV12, thus
crashing the driver.
This patchs moves the call to a slightly later spot, at which point only
YUV and NV12 modes are handled.

There is a problem related to DSS FIFO thresholds and power management
on OMAP3. It seems that when the full PM hits in, we get underflows. The
core reason is unknown, but after experiments it looks like only
particular FIFO thresholds work correctly.
This bug is related to an earlier patch, which added special FIFO
threshold configuration for OMAP3, because DSI command mode output
didn't work with the normal threshold configuration.
However, as the above work-around worked fine for other output types
also, we currently always configure thresholds in this special way on
OMAP3. In theory there should be negligible difference with this special
way and the standard way. The first paragraph explains what happens in
practice.
This patch changes the driver to use the special threshold configuration
only when the output is a manual update display on OMAP3. This does
include RFBI displays also, and although it hasn't been tested (no
boards using RFBI) I suspect the similar behaviour is present there
also, as the DISPC side should work similarly for DSI command mode and
RFBI.

DSI supports interleaving of command mode packets during the HSA, HFP, HBP and
BLLP blanking intervals in a video mode stream. This is useful as a user may
want to read or change the configuration of a panel without stopping the video
stream.
On OMAP DSI, we can queue HS or LP command mode packets in the TX FIFO, and
the DSI HW takes care of interleaving this data during the one of the blanking
intervals. The DSI HW needs to be programmed with the maximum amount of data
that can be interleaved in a particular blanking period. A blanking period
cannot be used to send command mode data for it's complete duration, there is
some amount of time required for the DSI data and clock lanes to transition
to the desired LP or HS state.
Based on the state of the lanes at the beginning and end of the blanking period,
we have different scenarios, with each scenario having a different value of time
required to transition to HS or LP. Refer to the section 'Interleaving Mode' in
OMAP TRM for more info on the scenarios and the equations to calculate the time
required for HS or LP transitions.
We use the scenarios which takes the maximum time for HS or LP transition, this
gives us the minimum amount of time that can be used to interleave command mode
data. The amount of data that can be sent during this minimum time is calculated
for command mode packets both in LP and HS. These are written to the registers
DSI_VM_TIMING4 to DSI_VM_TIMING6.
The calculations don't take into account the time required of transmitting BTA
when doing a DSI read, or verifying if a DSI write went through correctly. Until
these latencies aren't considered, the behaviour of DSI is unpredictable when
a BTA is interleaved during a blanking period. Enhancement of these calculations
is a TODO item.
The calculations are derived from DSI parameter calculation tools written by

DISPC has two accumulator registers DISPC_VIDp_ACCU_0 and DISPC_VIDp_ACCU_1 each
with horizontal and vertical bit fields. The bit fields can take values in the
range of -1024 to 1023. Based on bit field values DISPC decides on which one out
of 8 phases the filtering starts. DISPC_VIDp_ACCU_0 is used for progressive
output and for interlaced output both DISPC_VIDp_ACCU_0 and DISPC_VIDp_ACCU_1
are used.
The current accumulator values in DISPC scaling logic for chroma plane takes
default values for all color modes and rotation types. So, the horizontal and
vertical up and downsampling accumulator bit field values have been updated for
better performance.

The THRESHOLDS register configures thresholds for two interrupts, but
these interrupts are not used in the DIU driver. An early version of the
driver may have used the "lines before vsync" interrupt, which requires
the LS_BF_VS of THRESHOLDS to be initialized.
Unfortunately, the initialization of this register does not do a
read-modify-write to set only LS_BF_VS. On the MPC8610, the value
written is correct. On other chips, like the P1022, the value overwrites
some reserved bits. This results in a performance drop on the P1022.
Since the default value is acceptable as-is on all SOCs, we should just
avoid touching this register.

Implement the DSS device driver audio support interface in the HDMI
panel driver and generic driver. The implementation relies on the
IP-specific functions that are defined at DSS probe time.
A mixed locking strategy is used. The panel's mutex is used when
the state of the panel is queried as required by the audio functions.
The audio state is protected using a spinlock as users of DSS HDMI
audio functionality might start/stop audio while holding a spinlock.
The mutex and the spinlock are held and released as needed by each
individual function to protect the panel state and the audio state.
Although the panel's audio_start functions does not check whether
the panel is active, the audio _ENABLED state can be reached only
from audio_enable, which does check the state of the panel. Also,
if the panel is ever disabled, the audio state will transition
to _DISABLED. Transitions are always protected by the audio lock.

As of today, the only know user of the DSS HDMI audio support is
ASoC. Hence, it makes sense to remap the speaker order to match
the ALSA speaker order. In the future, a dynamic mapping mechanism
may be implemented.
Remapping is needed as the HDMI speaker order is FL/FR/LFE/C/RL/RR/
RLC-FLC/RRC-FLC while the ALSA order is FL/FR/RL/RR/C/LFE/SL/SR.
Refer to CEA-861 Section 6.6.2 for further details.

The generic HDMI driver does not need to know about the specific
settings of a given IP. Hence, it just passes the audio configuration
and the IP library parses such configuration and sets the IP
accordingly. This patch introduces an IP-specific audio configuration
function.
Also, this patch implements the audio config function for OMAP4. The
DMA, format and core config functions are no longer exposed to the
generic HDMI driver as they are IP-specific.
The audio configuration function caters for 16-bit through 24-bit
audio samples with sample rates from 32kHz and up to 192kHz as well
as up to 8 audio channels.

The N and CTS parameters are relevant to all HDMI implementations and
not specific to a given IP. Hence, the calculation is relocated
into the generic HDMI driver.
Also, deep color is not queried but it is still considered in the
calculation of N. This is to be changed when deep color functionality is
implemented in the driver.

We currently use the id of the dsi platform device (dsidev->id) as the
DSI hardware module ID. This works because we assign the ID manually in
arch/arm/mach-omap2/display.c at boot time.
However, with device tree the platform device IDs are automatically
assigned to an arbitrary number, and we can't use it.
Instead of using dsidev->id during operation, this patch stores the
value of dsidev->id to a private field of the dsi driver at probe(). The
future device tree code can thus set the private field with some other
way.

Now that each output driver creates their own display devices, the

Currently the higher level omapdss platform driver gets the list of
displays in its platform data, and uses that list to create the
omap_dss_device for each display.
With DT, the logical way to do the above is to list the displays under
each individual output, i.e. we'd have "dpi" node, under which we would
have the display that uses DPI. In other words, each output driver
handles the displays that use that particular output.
To make the current code ready for DT, this patch modifies the output
drivers so that each of them creates the display devices which use that
output. However, instead of changing the platform data to suit this
method, each output driver is passed the full list of displays, and the
drivers pick the displays that are meant for them. This allows us to
keep the old platform data, and thus we avoid the need to change the
board files.

We currently have a two ways to set a "default panel device" for dss, to
which the overlays are connected when the omapdss driver is loaded:
- in textual format (name of the display) as cmdline parameter
- as a pointer to the panel device from board file via pdata
The current code handles this in a bit too complex way by using both of
the above methods during runtime. However, with DT we don't have pdata
anymore, so the code handling the second case won't work anymore. The
current code has also the problem that it modifies the platform_data.
This patch simplifies the code a bit by using the pointer method only
inside the probe function, and stores the name of the panel device. This
way we only need to handle the textual format during operation and also
avoid modifying the platform_data.

We currently have separate device/driver for each DSS HW module. The DPI
and SDI outputs are more or less parts of the DSS or DISPC hardware
modules, but in SW it makes sense to represent them as device/driver
pairs similarly to all the other outputs. This also makes sense for
device tree, as each node under dss will be a platform device, and
handling DPI & SDI somehow differently than the rest would just make the
code more complex.

The omapdss pdata handling is a mess. This is more evident when trying
to use device tree for DSS, as we don't have platform data anymore in
that case. This patch cleans the pdata handling by:
- Remove struct omap_display_platform_data. It was used just as a
wrapper for struct omap_dss_board_info.
- Pass the platform data only to omapdss device. The drivers for omap
dss hwmods do not need the platform data. This should also work better
for DT, as we can create omapdss device programmatically in generic omap
boot code, and thus we can pass the pdata to it.
- Create dss functions for get_ctx_loss_count and dsi_enable/disable_pads
that the dss hwmod drivers can call.

In 2009 Philip Reiser notied that a few users of netlink connector
interface needed a capability check and added the idiom
cap_raised(nsp->eff_cap, CAP_SYS_ADMIN) to a few of them, on the premise
that netlink was asynchronous.
In 2011 Patrick McHardy noticed we were being silly because netlink is
synchronous and removed eff_cap from the netlink_skb_params and changed
the idiom to cap_raised(current_cap(), CAP_SYS_ADMIN).
Looking at those spots with a fresh eye we should be calling
capable(CAP_SYS_ADMIN). The only reason I can see for not calling capable
is that it once appeared we were not in the same task as the caller which
would have made calling capable() impossible.
In the initial user_namespace the only difference between between
cap_raised(current_cap(), CAP_SYS_ADMIN) and capable(CAP_SYS_ADMIN) are a
few sanity checks and the fact that capable(CAP_SYS_ADMIN) sets
PF_SUPERPRIV if we use the capability.
Since we are going to be using root privilege setting PF_SUPERPRIV seems
the right thing to do.
The motivation for this that patch is that in a child user namespace
cap_raised(current_cap(),...) tests your capabilities with respect to that
child user namespace not capabilities in the initial user namespace and
thus will allow processes that should be unprivielged to use the kernel
services that are only protected with cap_raised(current_cap(),..).
To fix possible user_namespace issues and to just clean up the code
replace cap_raised(current_cap(), CAP_SYS_ADMIN) with
capable(CAP_SYS_ADMIN).

The DPI and HDMI interfaces use their 'set_timing' functions to take in a new

When checking overlay and manager data, the DSS driver uses the last applied
manager timings, and not the timings held by omap_dss_device struct. Hence,

If a manager is disabled, there is no guarantee at any point in time that all
it's parameters are configured. There is always a chance that some more
parameters are yet to be configured by a user of DSS, or by DSS itself.
However, when the manager is enabled, we can be certain that all the parameters
have been configured, as we can't enable a manager with an incomplete
configuration. Therefore, if a manager is disabled, don't check for the validity
of it's parameters or the parameters of the overlays connected to it. Only check
once it is enabled. Add a check in dss_check_settings_low() to achieve the same.

In preparation for device tree, this patch changes how the DSI pins are
configured. The current configuration method is only doable with board
files and the configuration data is OMAP specific.
This patch moves the configuration data to the panel's platform data,
and the data can easily be given via DT in the future. The configuration
data format is also changed to a generic one which should be suitable
for all platforms.
The new format is an array of pin numbers, where the array items start
from clock + and -, then data1 + and -, and so on. For example:
{
0, // pin num for clock lane +
1, // pin num for clock lane -
2, // pin num for data1 lane +
3, // pin num for data1 lane -
...
}
The pin numbers are translated by the DSI driver and used to configure
the hardware appropriately.

Merge tag 'v3.4-rc6' into drm-intel-next
Conflicts:
drivers/gpu/drm/i915/intel_display.c
Ok, this is a fun story of git totally messing things up. There
/shouldn't/ be any conflict in here, because the fixes in -rc6 do only
touch functions that have not been changed in -next.
The offending commits in drm-next are 14415745b2..1fa611065 which
simply move a few functions from intel_display.c to intel_pm.c. The
problem seems to be that git diff gets completely confused:
$ git diff 14415745b2..1fa611065
is a nice mess in intel_display.c, and the diff leaks into totally
unrelated functions, whereas
$git diff --minimal 14415745b2..1fa611065
is exactly what we want.
Unfortunately there seems to be no way to teach similar smarts to the
merge diff and conflict generation code, because with the minimal diff
there really shouldn't be any conflicts. For added hilarity, every
time something in that area changes the + and - lines in the diff move
around like crazy, again resulting in new conflicts. So I fear this
mess will stay with us for a little longer (and might result in
another backmerge down the road).

In OMAP3 DISPC video overlays suffer from some undocumented horizontal position
and timing related limitations leading to SYNCLOST errors. Whenever the image
window is moved towards the right of the screen SYNCLOST errors become
frequent. Checks have been implemented to see that DISPC driver rejects
configuration exceeding above limitations.
This code was successfully tested on OMAP3. This code is written based on code
written by Ville Syrjälä <ville.syrjala@nokia.com> in Linux OMAP kernel. Ville
Syrjälä <ville.syrjala@nokia.com> had added checks for video overlay horizontal
timing and DISPC horizontal blanking length limitations.

In OMAP3 and OMAP4, the DISPC Scaler can downscale an image up to 4 times, and
up to 2 times in OMAP2. However, with predecimation, the image can be reduced
to 16 times by fetching only the necessary pixels in memory. Then this
predecimated image can be downscaled further by the DISPC scaler.
The pipeline is configured to use a burst of size 8 * 128 bits which consists
of 8 mini bursts of 16 bytes each. So, horizontal predecimation more than 16
can lead to complete discarding of such mini bursts. L3 interconnect may
handover the bus to some other initiator and inturn delay the fetching of
pixels leading to underflows. So, maximum predecimation limit is fixed at 16.
Based on the downscaling required, a prior calculation of predecimation values
for width and height of an image is done. Since, Predecimation reduces quality
of an image higher priorty is given to DISPC Scaler for downscaling.
This code was successfully tested on OMAP2, OMAP3 and OMAP4. Horizontal and
vertical predecimation worked fine except for some synclost errors due to
undocumented errata in OMAP3 which are fixed later and skewed images were seen
on OMAP2 and OMAP3 during horizontal predecimation which will be addressed in
the future patches.
This code is based on code written by Lajos Molnar <lajos@ti.com> who had added
predecimation support for NV12/YUV/rotated/SDMA buffers.

With this optional callback the driver is notified when the first page
is entered into the pagelist and a new deferred_io call is scheduled.
A possible use-case for this is runtime-pm. In the first_io call
pm_runtime_get()
could be called, which starts an asynchronous runtime_resume of the
device. In the deferred_io callback a call to
pm_runtime_barrier()
makes the sure, the device is resumed by then and a
pm_runtime_put()
may put the device back to sleep.
Also, some SoCs may use the runtime-pm system to determine if they
are able to enter deeper idle states. Therefore it is necessary to
keep the use-count from the first written page until the conclusion
of the screen update, to prevent the system from going to sleep before
completing the pending update.
Two users of defio were using kmalloc to allocate the structure.
These allocations are changed to kzalloc, to prevent uninitialised
.first_io members in those drivers.

Currently, a LCD manager's timings is set by dispc_mgr_set_lcd_timings() and TV
manager's timings is set by dispc_set_digit_size(). Use a common function called
dispc_mgr_set_timings() which sets timings for both type of managers.
We finally want the interface drivers to use an overlay manager function to
configure it's timings, having a common DISPC function would make things
cleaner.
For LCD managers, dispc_mgr_set_timings() sets LCD size and blanking values, for
TV manager, it sets only the TV size since blanking values don't exist for TV.

Since any power on stabilisation delay for the supply itself should be
taken care of transparently by the regulator API when the regulator is
enabled the additional delay that the TPO-TD03MTEA1 driver adds after
that returned should be due to the requirements of the device itself
rather than the supply (the delay is also suspicously long for one for
a regulator to ramp). Correct the comment to avoid misleading people

The TAAL driver contains some regulator support which is currently unused
(the code is there but the one panel supported by the driver doesn't have
any regulators provided). This code mostly looks like an open coded
version of the regulator core bulk API.
The only additional feature is that a voltage range can be set once when
the device is opened, though this is never varied at runtime. The general
expectation is that if the device is not actively managing the voltage of
the device (eg, doing DVFS) then any configuration will be done using the
constraints rather than by drivers, saving them code and ensuring that
they work well with systems where the voltage is not configurable.
If systems are added needing regulator support this can be added back in,
though it should be based on core features rather than open coding things.

For some OMAP versions the TRM says that the pixel clock from DISPC can
be used as an input clock for DSI PLL, instead of the default, which is
sysclk. For some OMAP versions the bits affecting this are marked as
reserved. This feature has never been tested, so it's unknown if the HW
even works, and has never been used.

Most of the DSS clocks have restrictions on their frequency based on the
OPP in use. For example, maximum frequency for a clock may be 180MHz in
OPP100, but 90MHz in OPP50. This means that when a high enough pixel
clock or function clock is required, we need to use OPP100.
However, there's currently no way in the PM framework to make that kind
of request. The closest we get is to ask for very high bus throughput
from the PM framework, which should effectively force OPP100.
This patch is a simple version for handling the problem. Instead of
asking for OPP100 only when needed, this patch asks for OPP100 whenever
DSS is active. This obviously is not an optimal solution for cases with
small displays where OPP50 would work just fine. However, a proper
solution is a complex one, and this patch is a short term solution for
the problem.

fixes a section mismatch between the board file and the driver's probe
function, however, it misses the additional mismatches between the
probe function and some routines it calls. Fix these up as well.

If wait_event_interruptible_timeout returns a positive value, it means
the condition evaluated is true. Which means priv->shared->hw_running is false.
And then we will exit the loop.

The decision to enable or disable the data output to the lcd panel from
the controller need not be based on the value of 'default_win' element
in the platform data. Instead, the data output to the panel is enabled
if any of the windows are active, else data output is disabled.

The video interface timing is independent of the window setup data.
The resolution of the window can be smaller than that of the lcd
panel to which the video data is output.
So move the video timing data from the per-window setup data to the
platform specific section in the platform data. This also removes
the restriction that atleast one window should have the same
resolution as that of the panel attached.

A bunch of fixes for regressions (and a few other problems) in 3.4-rc1:
* Fix for regression of mach/io.h cleanup on platforms with PCI or PCMCIA
(adding back the include file on those for now)
* AT91 fixes for usb and spi
* smsc911x ethernet fixes for i.MX
* smsc911x fixes for OMAP
* gpio fixes for Tegra
* A handful of build error and warning fixes for various platforms
* cpufreq kconfig dependencies, build and lowlevel debug fixes for
Samsung platforms
In other words, more or less the regular collection of -rc1/2 type
material. A few of them, in particular the smsc911x for OMAP series, aren't
technically regressions for 3.4, but they're valid fixes and we're still
relatively early in the rc cycle so it seems appropriate to include them.

I still need to send a few checkpoint/restore patches. I've been
wobbly about merging them because I'm wobbly about the overall

Merge tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system
Pull "Disintegrate and delete asm/system.h" from David Howells:
"Here are a bunch of patches to disintegrate asm/system.h into a set of
separate bits to relieve the problem of circular inclusion
dependencies.
I've built all the working defconfigs from all the arches that I can
and made sure that they don't break.
The reason for these patches is that I recently encountered a circular
dependency problem that came about when I produced some patches to
optimise get_order() by rewriting it to use ilog2().
This uses bitops - and on the SH arch asm/bitops.h drags in
asm-generic/get_order.h by a circuituous route involving asm/system.h.
The main difficulty seems to be asm/system.h. It holds a number of
low level bits with no/few dependencies that are commonly used (eg.
memory barriers) and a number of bits with more dependencies that
aren't used in many places (eg. switch_to()).
These patches break asm/system.h up into the following core pieces:
(1) asm/barrier.h
Move memory barriers here. This already done for MIPS and Alpha.
(2) asm/switch_to.h
Move switch_to() and related stuff here.
(3) asm/exec.h
Move arch_align_stack() here. Other process execution related bits
could perhaps go here from asm/processor.h.
(4) asm/cmpxchg.h
Move xchg() and cmpxchg() here as they're full word atomic ops and
frequently used by atomic_xchg() and atomic_cmpxchg().
(5) asm/bug.h
Move die() and related bits.
(6) asm/auxvec.h
Move AT_VECTOR_SIZE_ARCH here.
Other arch headers are created as needed on a per-arch basis."
Fixed up some conflicts from other header file cleanups and moving code
around that has happened in the meantime, so David's testing is somewhat
weakened by that. We'll find out anything that got broken and fix it..

Merge tag 'mfd_3.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
Pull MFD changes from Samuel Ortiz:
- 4 new drivers: Freescale i.MX on-chip Anatop, Ricoh's RC5T583 and
TI's TPS65090 and TPS65217.
- New variants support (8420, 8520 ab9540), cleanups and bug fixes for
the abx500 and db8500 ST-E chipsets.
- Some minor fixes and update for the wm8994 from Mark.
- The beginning of a long term TWL cleanup effort coming from the TI
folks.
- Various fixes and cleanups for the s5m, TPS659xx, pm860x, and MAX8997
drivers.
Fix up trivial conflicts due to duplicate patches and header file
cleanups (<linux/device.h> removal etc).

Pull ARM platform updates from Russell King:
"This covers platform stuff for platforms I have a direct interest in
(iow, I have the hardware). Essentially:
- as we no longer support any other Acorn platforms other than RiscPC
anymore, we can collect all that code into mach-rpc.
- convert Acorn expansion card stuff to use IRQ allocation functions,
and get rid of NO_IRQ from there.
- cleanups to the ebsa110 platform to move some private stuff out of
its header files.
- large amount of SA11x0 updates:
- conversion of private DMA implementation to DMA engine support
(this actually gives us greater flexibility in drivers over the old
API.)
- re-worked ucb1x00 updates - convert to genirq, remove sa11x0
dependencies, fix various minor issues
- move platform specific sa11x0 framebuffer data into platform files
in arch/arm instead of keeping this in the driver itself
- update sa11x0 IrDA driver for DMA engine, and allow it to use DMA
for SIR transmissions as well as FIR
- rework sa1111 support for genirq, and irq allocation
- fix sa1111 IRQ support so it works again
- use sparse IRQ support
After this, I have one more pull request remaining from my current
set, which I think is going to be the most problematical as it
generates 8 conflicts."
Fixed up the trivial conflict in arch/arm/mach-rpc/Makefile as per
Russell.

These changes are all specific to one board only. We're trying to keep
the number of board files low, but generally board level updates are
ok on platforms that are working on moving towards DT based probing,
which will eventually lead to removing them.
The board-ams-delta.c board file gets a conflict between the removal of
ams_delta_config and the addition of a lot of other data. The Kconfig
file has two changes in the same line, and in exynos, the power domain
cleanup conflicts with the addition of the image sensor device.

Add support for pandora (openpandora.org) backlight.
It might look like all this could be done using pwm_bl.c instead, but
there is a need of special programming sequence when turning on the LED
driver chip or else it will misbehave. Doing this using pwm_bl.c would
require to use some register programming and pwm functions from platform
code, and ARM maintainers are allergic to driver-like code in /arch/arm
nowadays. The PMIC PWM driver is currently missing too, so pwm_bl.c
can't be used anyway.

There is one thing in the Kconfig that you won't like: "default y

all depends on CONFIG_XEN which depends on CONFIG_PARAVIRT which by
default is off). I've a fix to convert that boolean expression

Pull drm main changes from Dave Airlie:
"This is the main drm pull request, I'm probably going to send two more
smaller ones, will explain below.
This contains a patch that is also in the fbdev tree, but it should be
the same patch, it added an API for hot unplugging framebuffer
devices, and I need that API for a new driver.
It also contains some changes to the i2c tree which Jean has acked,
and one change to moorestown platform stuff in x86.
Highlights:
- new drivers: UDL driver for USB displaylink devices, kms only,
should support correct hotplug operations.
- core: i2c speedups + better hotplug support, EDID overriding via
firmware interface - allows user to load a firmware for a broken
monitor/kvm from userspace, it even has documentation for it.
- exynos: new HDMI audio + hdmi 1.4 + virtual output driver
- gma500: code cleanup
- radeon: cleanups, CS optimisations, streamout support and pageflip
fix
- nouveau: NVD9 displayport support + more reclocking work
- i915: re-enabling GMBUS, finish gpu patch (might help hibernation
who knows), missed irq fixes, stencil tiling fixes, interlaced
support, aliasesd PPGTT support for SNB/IVB, swizzling for SNB/IVB,
semaphore fixes
As well as the usual bunch of cleanups and fixes all over the place.
I've got two things I'd like to merge a bit later:
a) AMD support for all their new radeonhd 7000 series GPU and APUs.
AMD dropped this a bit late due to insane internal review
processes, (please AMD just follow Intel and let open source guys
ship stuff early) however I don't want to penalise people who own
this hardware (since its been on sale for 3-4 months and GPU hw
doesn't exactly have a lifetime in years) and consign them to
using closed drivers for longer than necessary. The changes are
well contained and just plug into the driver new gpu functionality
so they should be fairly regression proof. I just want to give
them a bit of a run on the hw AMD kindly sent me.
b) drm prime/dma-buf interface code. This is just infrastructure
code to expose the dma-buf stuff to drm drivers and to userspace.
I'm not planning on pushing any driver support in this cycle
(except maybe exynos), but I'd like to get the infrastructure code
in so for the next cycle I can start getting the driver support
into the individual drivers. We have started driver support for
i915, nouveau and udl along with I think exynos and omap in
staging. However this code relies on the dma-buf tree being
pulled into your tree first since it needs the latest interfaces
from that tree. I'll push to get that tree sent asap.
(oh and any warnings you see in i915 are gcc's fault from what anyone
can see)."
Fix up trivial conflicts in arch/x86/platform/mrst/mrst.c due to the new
msic_thermal_platform_data() thermal function being added next to the
tc35876x_platform_data() i2c device function..

We do the dss driver registration in a rather strange way: we have the
higher level omapdss driver, and we use that driver's probe function to
register the drivers for the rest of the dss devices.
There doesn't seem to be any reason for that, and additionally the
soon-to-be-merged patch "ARM: OMAP: omap_device: remove
omap_device_parent" will break omapdss initialization with the current
registration model.
This patch changes the registration for all drivers to happen at the
same place, in the init of the module.

sh_mipi uses some clocks, but the method of setup depends on CPU.
Current SuperH (like sh73a0) can control all of these clocks
by CPG (Clock Pulse Generator).
It means we can control it by clock framework only.
But on sh7372, it needs CPG settings AND sh_mipi PHYCTRL::PLLDS,
and only sh7372 has PHYCTRL::PLLDS.
But on current sh_mipi driver, PHYCTRL::PLLDS of sh7372 was
overwrote since the callback timing of clock setting was changed
by c2658b70f0
(fbdev: sh_mipi_dsi: fixup setup timing of sh_mipi_setup()).
To solve this issue, this patch adds extra .phyctrl.
This patch adds detail explanation for unclear mipi settings
and fixup wrong PHYCTRL::PLLDS value for ap4evb (0xb -> 0x6).

Add timing data for Hitachi SP10Q010 display and allow configuration
of the 4bpp palette. For 4bpp framebuffer enable reversed order of
pixels in a byte. This requires defining FB_CFB_REV_PIXELS_IN_BYTE
and additionally setting var.nonstd to the value FB_NONSTD_REV_PIX_IN_B.
Note that it is not enough to set da8xx_fb_var.nonstd to this value
statically, since FBIOPUT_VSCREENINFO ioctl might pass var struct with
.nonstd field set to zero or another value. Therefore this setting must
be adjusted in fb_check_var() according to the requested bpp value.

PV-on-HVM guests may want to use the xen keyboard/mouse frontend, but
they don't use the xen frame buffer frontend. For this case it doesn't
make much sense for INPUT_XEN_KBDDEV_FRONTEND to depend on
XEN_FBDEV_FRONTEND. The opposite direction always makes more sense, i.e.
if you're using xenfb, then you'll want xenkbd. Switch the dependencies.

The USB graphics card driver delays the unregistering of the framebuffer
device to a workqueue, which breaks the userspace visible remove uevent
sequence. Recent userspace tools started to support USB graphics card
hotplug out-of-the-box and rely on proper events sent by the kernel.
The framebuffer device is a direct child of the USB interface which is
removed immediately after the USB .disconnect() callback. But the fb device
in /sys stays around until its final cleanup, at a time where all the parent
devices have been removed already.
To work around that, we remove the sysfs fb device directly in the USB
.disconnect() callback and leave only the cleanup of the internal fb
data to the delayed work.

The ep93xx backlight driver uses a single register within the
framebuffer's register space. Currently the backlight driver uses a
static IO mapping for the register since the memory cannot be
requested by both drivers.
Convert the static mapping to use ioremap so that we can remove the
dependency on mach/hardware.h. To do so, we need remove the
request_mem_region from both the backlight and framebuffer drivers,
since whichever driver is loaded second will fail with -EBUSY
otherwise.
A proper fix is still required, and a FIXME comment has been added to
both drivers.
