e29206381a viafb: fix IGA1 modesetting on VX900
Even if the documentation calls this bit "Reserved" it has to be set
to 0 for correct modesetting on IGA1.

050f0e02c8 viafb: select HW scaling on VX900 for IGA2
VX900 can do hardware scaling for both IGAs in contrast to previous
hardware which could do it only for IGA2. This patch ensures that
we set the parameter for IGA2 and not for IGA1. This fixes hardware
scaling on VX900 until we have the infrastructure to support it for
both IGAs.

ca888a7958 OMAPDSS: HDMI: hot plug detect fix
The "OMAPDSS: HDMI: PHY burnout fix" commit switched the HDMI driver
over to using a GPIO for plug detect.  Unfortunately the ->detect()
method was not also updated, causing HDMI to no longer work for the
omapdrm driver (because it would actually check if a connection was
detected before attempting to enable display).

a247ce78ca OMAPDSS: HACK: Ensure DSS clock domain gets out of idle when HDMI is enabled
For DSS clock domain to transition from idle to active state. It's necessary
to enable the optional clock DSS_FCLK before we enable the module using the
MODULEMODE bits in the clock domain's CM_DSS_DSS_CLKCTRL register.

This sequence was not followed correctly for the 'dss_hdmi' hwmod and it led
to DSS clock domain not getting out of idle when pm_runtime_get_sync() was
called for hdmi's platform device.

Since the clock domain failed to change it's state to active, the hwmod code
disables any clocks it had enabled before for this hwmod. This led to the clock
'dss_48mhz_clk' gettind disabled.

When hdmi's runtime_resume() op is called, the call to dss_runtime_get()
correctly enables the DSS clock domain this time. However, the clock
'dss_48mhz_clk' is needed for HDMI's PHY to function correctly. Since it was
disabled previously, the driver fails when it tries to enable HDMI's PHY.

Fix this for now by ensuring that dss_runtime_get() is called before we call
pm_runtime_get_sync() for hdmi's platform device. A correct fix for later would
be to modify the DSS related hwmod's mainclks, and also some changes in how
opt clocks are handled in the DSS driver.

This fixes the issue of HDMI not working when it's the default display. The
issue is not seen if any other display is already enabled as the first display
would have correctly enabled the DSS clockdomain.

80277566d0 OMAPFB: remove mem info from platform_data
omapfb driver used platform_data to get fb memory areas and formats
defined by the board file.

This patch removes omapfb's (both old and new omapfb) use of the
memory data in platform_data, because:

- No board uses them currently
- It's not board file's job to define things like amount of default
  framebuffer memory. These should come from the bootloader via command
  line parameters.

58e0d6ab02 OMAP: N770: remove HWA742 platform data
In an effort to clean up the old omapfb driver, this patch removes
HWA742 (the display chip used in N770) platform data. This can be done
as N770 is the only user of HWA742, and the platform data contains only
one field, te_connected, which we can just presume to be true in the
HWA742 driver.

This allows us to remove omapfb_set_ctrl_platform_data(), and the
mechanism to pass the platform data, in a later patch.

7258cc14f3 video: support MIPI-DSI controller driver
Samsung S5PC210 and EXYNOS SoC platform has MIPI-DSI controller and
MIPI-DSI based LCD Panel could be used with it.  This patch supports
MIPI-DSI driver based Samsung SoC chip.

LCD panel driver based MIPI-DSI should be registered to MIPI-DSI driver at
machine code and LCD panel driver specific function registered to
mipi_dsim_ddi structure at lcd panel init function called system init.  In
the MIPI-DSI driver, find lcd panel driver by using registered lcd panel
name, and then initialize lcd panel driver.

e75892715d viafb: add auxiliary device management infrastructure
This patch adds the basic infrastructure and a few stub drivers for
devices that are connected via I2C busses. The infrastructure will
be used to replace and extend the support that is scattered
throughout viafb. The stub drivers are not very useful yet but they
show how the infrastructure works, provide information about the
chips integrated into a system and maybe gather some testers as it
would be very difficult for a single person to get a sane test
environment.
The only thing this actually does is probing the I2C busses which
will hopefully not cause any regressions.

4041071571 ARM: omap: fix oops in drivers/video/omap2/dss/dpi.c
When a PMIC is not found, this driver is unable to obtain its
'vdds_dsi_reg' regulator.  Even through its initialization function
fails, other code still calls its enable function, which fails to
check whether it has this regulator before asking for it to be enabled.

This fixes the oops, however a better fix would be to sort out the
upper layers to prevent them calling into a module which failed to
initialize.

92a9c19a89 udlfb: remove sysfs framebuffer device with USB .disconnect()
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.

Before:
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb0 (graphics)
 remove   /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)
 remove   /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 remove   /2-1.2:1.0/graphics/fb0 (graphics)

After:
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb)
 add      /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics)
 remove   /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics)

f820917aba video: da8xx-fb: reset LCDC only if functional clock changes with DVFS
LCDC functional clock may or may not be derived from CPU/MPU DPLL,
For example,
AM335x => Separate independent DPLL for LCDC
Davinci => Same DPLL as MPU

So, on platforms where LCDC functional clock is not derived from CPU/MPU
PLL it is not required to reset LCDC module as its functional clock does
not change with DVFS.

This patch adds check to do reset only if functional clock changes
between pre and post notifier callbacks with DVFS.

c49d005b6c OMAPDSS: HDMI: PHY burnout fix
A hardware bug in the OMAP4 HDMI PHY causes physical damage to the board
if the HDMI PHY is kept powered on when the cable is not connected.

This patch solves the problem by adding hot-plug-detection into the HDMI
IP driver. This is not a real HPD support in the sense that nobody else
than the IP driver gets to know about the HPD events, but is only meant
to fix the HW bug.

The strategy is simple: If the display device is turned off by the user,
the PHY power is set to OFF. When the display device is turned on by the
user, the PHY power is set either to LDOON or TXON, depending on whether
the HDMI cable is connected.

The reason to avoid PHY OFF when the display device is on, but the cable
is disconnected, is that when the PHY is turned OFF, the HDMI IP is not
"ticking" and thus the DISPC does not receive pixel clock from the HDMI
IP. This would, for example, prevent any VSYNCs from happening, and
would thus affect the users of omapdss. By using LDOON when the cable is
disconnected we'll avoid the HW bug, but keep the HDMI working as usual
from the user's point of view.

0eaf9f52e9 OMAPDSS: use sync versions of pm_runtime_put
omapdss doesn't work properly on system suspend. The problem seems to be
the fact that omapdss uses pm_runtime_put() functions when turning off
the hardware, and when system suspend is in process only sync versions
are allowed.

Using non-sync versions normally and sync versions when suspending would
need rather ugly hacks to convey the information of
suspending/not-suspending to different functions. Optimally the driver
wouldn't even need to care about this, and the PM layer would handle
syncing when suspend is in process.

This patch changes all omapdss's pm_runtime_put calls to
pm_runtime_put_sync. This fixes the suspend problem, and probably the
performance penalty of always using sync versions is negligible.

Take fifo merge into use by implementing a rather naive fifo merge
threshold calculation: keep the low threshold always the same, but
increase the high threshold when fifo merge is used.

This should greatly increase the time between pixel data fetches from
SDRAM, as the usable fifo size is much larger. However, it probably
won't help for fifo underflows, as the low threshols is kept the same.

1d71f42b35 OMAPDSS: APPLY: add fifo-merge support
Add fifo-merge support. This is done mainly in four functions:
mgr_enable/disable and ovl_enable/disable. These are the functions where
overlays are taken into and out of active use.

The process to enable and disable fifo-merge is not simple. We need to
do it in steps, waiting in between for certain settings to be taken into
use, and continuing after that. The reason for this is that fifo-merge
is a common thing for all managers/overlays, and its use must be
synchronized.

As an example, when we disable an overlay, we first set the overlay as
disabled, then wait until the overlay is actually disabled in the HW,
and only after that we may re-configure the fifos, possibly taking
fifo-merge into use.

90ab5ee941 module_param: make bool parameters really bool (drivers & misc)
module_param(bool) used to counter-intuitively take an int.  In
fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy
trick.

It's time to remove the int/unsigned int option.  For this version
it'll simply give a warning, but it'll break next kernel version.

The function hdmi_audio_trigger is a callback used by ASoC to stop/start

Hence, it should be placed in the general portion of the HDMI driver,
along with the other ASoC callbacks.

Also, make this function static.

284cb318c8 ASoC: OMAP: HDMI: Correct signature of ASoC functions
These functions require access to IP-secific data. However, it is not possible
to pass such data as a function argument as such functions have a specific
signature specified by ASoC. Instead, they will have access to the IP-specific

b17ce11732 ASoC: OMAP: HDMI: Introduce driver data for audio codec
Under the new DSS architecture for HDMI, there is a clear separation
between general DSS code and HDMI IP-specific data. Functions
that require access to the HDMI driver IP-specific data receive an
hdmi_ip_data structure. The ASoC codec require access to such
IP-specific data. Then, instead of accessing it directly, it will be
passed as codec driver data. This also helps to have a clear separation
between DSS and ASoC portions of the code.

73db144b58 Xen: consolidate and simplify struct xenbus_driver instantiation
The 'name', 'owner', and 'mod_name' members are redundant with the
identically named fields in the 'driver' sub-structure. Rather than
switching each instance to specify these fields explicitly, introduce
a macro to simplify this.

Eliminate further redundancy by allowing the drvname argument to
DEFINE_XENBUS_DRIVER() to be blank (in which case the first entry from
the ID table will be used for .driver.name).

Also eliminate the questionable xenbus_register_{back,front}end()
wrappers - their sole remaining purpose was the checking of the
'owner' field, proper setting of which shouldn't be an issue anymore
when the macro gets used.

v2: Restore DRV_NAME for the driver name in xen-pciback.

f4f514734e video: s3c-fb: Take a runtime PM reference when unblanked
When the framebuffer is unblanked hold a runtime PM reference. This
prevents us powering down when userspace has left an image on the
framebuffer and prepares the way for being able to power down the hardware
when an application still has the device open.

Since we now hold a runtime PM reference whenever the display is unblanked
there is no need for the runtime power management to disable and enable
the display, and doing so would lead to runtime PM trying to recurse into
itself when called from the blanking code, so split the runtime PM into
separate functions which only deal with the clocks.  The PM core will
runtime resume the device prior to system suspend.

fe05f8b1c3 video: s3c-fb: Make runtime PM functional again
The change in "video: s3c-fb: modify runtime pm functions" (commit
35784b) renders the runtime power management for the device completely
ineffectual as while it leaves runtime power management notionally
enabled a runtime power reference is held for the entire time the device
is registered meaning it will never actually do anything.

A further issue is introduced as runtime power management is added
during the system suspend path which is not something which drivers are
supposed to do and would interact poorly if there were any operations
done in the runtime power management callbacks.

While this does make things simpler (the main motivation for the
original change) it will not only cause us to use more power in the
framebuffer controller but will also prevent us entering lower power
domain and SoC wide states as we can never power down the domain
containing the device.  Since neither of these things is desirable
revert the change.

1bb0b7d215 offb: Fix setting of the pseudo-palette for >8bpp
When using a >8bpp framebuffer, offb advertises truecolor, not directcolor,
and doesn't touch the color map even if it has a corresponding access method
for the real hardware.

Thus it needs to set the pseudo-palette with all 3 components of the color,
like other truecolor framebuffers, not with copies of the color index like
a directcolor framebuffer would do.

This went unnoticed for a long time because it's pretty hard to get offb
to kick in with anything but 8bpp (old BootX under MacOS will do that and
qemu does it).

We rename the mach64 hack to "simple" since that's also applicable
to anything using VGA-style DAC IO ports (set to 8-bit DAC) and we
use it for qemu vga.

Note that this is keyed on a device-tree "compatible" property that
is currently only set by an upcoming version of SLOF when using the
qemu "pseries" platform. This is on purpose as other qemu ppc platforms
using OpenBIOS aren't properly setting the DAC to 8-bit at the time of
the writing of this patch.

We can fix OpenBIOS later to do that and add the required property, in
which case it will be matched by this change.

7282f1b7c9 OMAPDSS: DISPC: Update Scaling Clock Logic
Clock requirements for scaling in OMAP2, OMAP3 and OMAP4 are different. In
OMAP2 and OMAP3 the required clock rate is a function of pixel clock, vertical
downscale ratio and horizontal downscale ratio whereas in OMAP4 it is a
function of pixel clock and horizontal downscale ratio only. Selection of 3-tap
vs 5-tap coefficients depends on clock rate line buffer width in OMAP3 whereas
in OMAP4 it is independent of clock rate and line buffer width. In OMAP2 3-tap
for vertical and 5-tap for horizontal scaling is used. In OMAP4 5-tap is used
both for horizontal and vertical scaling for better performance. Also, the
number and width of line buffers differs in OMAP3 and OMAP4.

So, clock functions have been fined tuned for OMAP3 and support has been added
added for OMAP4. This code has been tested on OMAP2, OMAP3 and OMAP4, and
scaling issues due to clock errors have been resolved.

debd90749b OMAPDSS: DISPC: Update Fir Coefficients
The FIR coefficients present in kernel are being updated to new coefficients
consisting of 24 coefficient tables, with 12 each for 3 tap and 5 tap scenario,
which are chosen on the basis of DISPC up/downsampling filters M value. M is
the inverse of low pass cut off frequency of the sampling filter. For vertical
scaling 3 tap or 5 tap tables are used based on the clock rate and width of
the line buffer whereas in OMAP2 3 tap is always used. For horizontal scaling
however 5 tap tables are always used.

New coefficients and the corresponding logic have been tested on OMAP2, OMAP3
and OMAP4. Horizontal and vertical scaling worked fine except for some 3 tap
vs 5 tap issue during vertical upscaling and clock failing issues which is
acknowledged in the next patch. Vertical upscaling was found to perform better
under 5 taps. The 24 coefficient tables have been moved to another file
dispc_coefs.c for proper maintainance.

This code is written based on code written by Lajos Molnar <lajos@ti.com> in
Android Kernel for scaling. Lajos Molnar <lajos@ti.com> had fine tuned the FIR
coefficient selection process and reduced outliness and blockiness around
images when upscaling more than 2 times.

b779505282 drivers/video: fsl-diu-fb: rename "machine_data" to "data"
"machine_data" is too long and clunky, and the "machine" part doesn't make

35784b4315 video: s3c-fb: modify runtime pm functions
Runtime suspend and runtime resume are modified in order to
reduce the complexity and improve the usability of runtime pm.
After probe function, s3c-fb driver is not suspended until
suspend or remove is called.

The scheme is changed as follows:
 runtime_get is only called in probe and resume.
 runtime_put is only called in remove and suspend.
 open/close cannot call the runtime_get/put.

Also, runtime_susepnd/resume are just called by runtime pm,
not doing suspend/resume routine any longer. This is because
open/close cannot call the runtime_get/put; the suspend/resume
routine in runtime_suspend/resume were previously used when
open and close were called.

The name of s3c-fb dev_pm_ops is changed from s3cfb_pm_ops to
s3c_fb_pm_ops in order to use more consistent naming.

ddd3d90543 drivers/video: fsl-diu-fb: merge all allocated data into one block
The Freescale DIU driver allocates multiple blocks of memory, including
multiple DMA buffers.  Merge all of these blocks into one data structure.

Specifically:

1) struct fsl_diu_data now contains everything that needs to be allocated,
except for the framebuffers themselves.  DMA'able objects are aligned correctly
within the structure.

2) struct diu_addr is no longer needed, because we don't have to manage
multiple blocks of DMA memory.

3) Since there's no diu_addr any more, macro DMA_ADDR is used to calculate
the DMA address of any field in fsl_diu_data.

4) Functions allocate_buf() and free_buf() are no longer needed, because we
now assume that dma_alloc_coherent() will allocate a page-aligned block,
and everything is properly aligned with fsl_diu_data already, so we no longer
need to align any memory blocks ourselves.

5) The "dummy" area descriptor is now defined separately from the other
five ADs, so NUM_AOIS (previously called FSL_AOI_NUM) is now set to five
instead of six.  Previously, all six were combined together to avoid a
separate call to allocate_buf() just for the dummy AD.

6) framebuffer_alloc() and framebuffer_release() are no longer used.  The
framebuffer is initialized manually.

7) Error handling is simplified since there's only one memory buffer
allocated.

f910fb8fcd video i.MX IPU: Fix display connections
The IPU internally works on 32bit colors. It can arbitrarily map
between pixel formats and internal representation and also between
internal representation and the physical connection to the display.
The driver used to change the mapping between internal representation
and display connection depending on the user selected bpp which is
wrong. Instead, the mapping is specified by the hardware, so an
additional field in platform data is added to describe the connection
between i.MX and the display. The default for this field is RGB666
which seems to be the only configuration which works without this
patch, so I assumed that all in Kernel boards are connected this
way.
This patch has been tested on a RGB666 connected display and a
RGB888 connected display in both 16bpp and 32bpp modes.

82153eda07 OMAPDSS: APPLY: add op->enabling
When we are enabling an overlay, there's a point in time when the
overlay is not actually enabled yet (nor do we want it to be enabled),
but we do want to check if the configuration for the overlay is valid,
and to calculate correct fifo thresholds for the soon-to-be-enabled
overlay.

Current code handled this in a hacky way, setting op->enabled to true
temporarily when calling functions that need to consider the state when
the overlay is enabled.

This patch makes this a bit cleaner, adding "enabling" field, which is
set when the overlay is not yet enabled but should be considered in the
checks and calculations.
