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
taking this code as a reference.

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.
To clean things up, this patch removes the functionality. This should
not affect any board.

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.

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.

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..

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."

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.

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.

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

THis driver supports TI LP8550/LP8551/LP8552/LP8553/LP8556 backlight
devices.
The brightness can be controlled by the I2C or PWM input. The lp855x
driver provides both modes. For the PWM control, pwm-specific functions
can be defined in the platform data. And some information can be read
via the sysfs(lp855x device attributes).
For details, please refer to Documentation/backlight/lp855x-driver.txt.

"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

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

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.

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.

Currently the shadow-dirty flags for manual update displays is cleared
in the apply_irq_handler when an update has finished. This is not
correct, as the shadow registers are taken into use (i.e. after that
they are not dirty) when the update is started.
Move the mgr_clear_shadow_dirty() call from apply_irq_handler to
dss_mgr_start_update() to fix this.

wait_pending_extra_info_updates() currently does a hacky second check
for extra_info_update_ongoing() at the end of the function to show a
warning if extra_info update is still ongoing. The call to
extra_info_update_ongoing() should really be inside spinlock, but that's
a bit heavy just for verification.
Rather than that, check the return value of the
wait_for_completion_timeout() and print an error if it has timeouted or
returned an error.
Even better would be to return the error value and act on it in the
callers of wait_pending_extra_info_updates. However, it's not clear what
the callers should do in case of an error, as the error should only
happen if there's a bug in the driver or the HW. So we'll just print the
warning for now.

ovl->enable/disable are meant to be synchronous so that they can handle
the configuration of fifo sizes. The current kernel doesn't configure
fifo sizes yet, and so the code doesn't need to block to function (from
omapdss driver's perspective).
However, for the users of omapdss a non-blocking ovl->disable is
confusing, because they don't know when the memory area is not used
any more.
Furthermore, when the fifo size configuration is added in the next merge
window, the change from non-blocking to blocking could cause side
effects to the users of omapdss. So by making the functions block
already will keep them behaving in the same manner.
And, while not the main purpose of this patch, this will also remove the
compile warning:

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).

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.

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

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.

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.

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.

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.

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.

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.

Add mechanism to set/unset the DISPC fifo-merge:
Add new fields to dss_data, fifo_merge and fifo_merge_dirty. These are
similar to the other info/dirty flags in ovl_priv_data and ovl_mgr_data,
but fifo merge is a common attribute to all managers and thus outside
the ovl_mgr_data.
The fifo-merge field is used in the dss_write_regs_common, which handles
writing the register.
dss_apply_fifo_merge() can be used to set/unset the fifo merge field in
the dss_data.

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.

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.

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.

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.

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.

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.

The driver says "module_param(ddc3, bool, 0);". But it's not a used
as a bool, it's used as a count.
Make it a bool.

This patch converts the drivers in drivers/video/pnx4008/* to use the
module_platform_driver() macro which makes the code smaller and a bit

Last but not least, create a much needed fbdev API documentation and

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.

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.

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.
