omapdss has its own video-timings struct, but we want to move the common
videomode.
The first step is to change the omapdss's pixelclock unit from kHz to
Hz. Also, omapdss uses "pixel_clock" field name, whereas the common
videomode uses "pixelclock" field name. This patch changes the field
name also, as that makes it easy to spot any non-converted pixel_clock
uses.

Nothing particularly stands out in this pull request. The biggest part of the
changes are cleanups.
Maybe one fix to mention is the "fb: reorder the lock sequence to fix potential
dead lock" which hopefully fixes the fb locking issues reported by multiple
persons.
There are also a few commits that have changes to arch/arm/mach-at91 and
arch/avr32, which have been acked by the maintainers.

Exynos Display Port can be used only for Exynos SoCs. In addition,
non-DT for EXYNOS SoCs is not supported from v3.11; thus, there is
no need to support non-DT for Exynos Display Port.
The 'include/video/exynos_dp.h' file has been used for non-DT
support and the content of file include/video/exynos_dp.h is moved
to drivers/video/exynos/exynos_dp_core.h. Thus, the 'exynos_dp.h'
file is removed. Also, 'struct exynos_dp_platdata' is removed,

We could set rb swap in two modules: DMA controler input part and
dsi interface output part.
DMA input part is based on pix_fmt to set rbswap, dsi output interface
part will set rbswap based on platform dsi_rbswap configuration.
This patch include below change and enhancement:
1) The input format which support rbswap is based on RGB format,
eg. RGB565 indicates the source data in memory is that Red is [15~11],
Green is [10~5], Blue is [4:0], Red is MSB, Blue is LSB, but for the
display dma input default setting(rbswap = 0), it only support Blue
is [15~11], Green is [10~5], Red is [4:0], Red is LSB, Blue is MSB,
so for this format(RGB565), display controller need to set rbswap
= 1 and it can support the MSB/LSB correctly.
BGR/YUV format will not set it in mmp display driver.
2) The dsi output part of rbswap is depend on dsi_rbswap which is
defined in specific platfrom. For output dsi interface, it has this
feature to do rbswap again if it needs specifc byte sequence of RGB
byte for DSI panel.
eg. If display content is set RGB565 in memory and DMA input part set
rbswap in driver to support Red as MSB , Blue LSB, but dsi panel only
support Red as LSB, Blue as MSB, then it can use this feature.
If there is no this requirement of panel, this dsi output part is not
needed.

In the old panel device model we had omap_dss_output entities,
representing the encoders in the DSS block. This entity had "device"
field, which pointed to the panel that was using the omap_dss_output.
With the new panel device model, the omap_dss_output is integrated into
omap_dss_device, which now represents a "display entity". Thus the "device"
field, now in omap_dss_device, points to the next entity in the display
entity-chain.
This patch renames the "device" field to "dst", which much better tells
what the field points to.

In the old panel device model we had "outputs", which were the encoders
inside OMAP DSS block, and panel devices (omap_dss_device). The panel
devices had a reference to the source of the video data, i.e. reference
to an "output", in a field named "output".
That was somewhat confusing even in the old panel device model, but even
more so with the panel device model where we can have longer chains of
display entities.
This patch renames the "output" field to "src", which much better tells
what the field points to.

Pull drm updates from Dave Airlie:
"Okay this is the big one, I was stalled on the fbdev pull req as I
stupidly let fbdev guys merge a patch I required to fix a warning with
some patches I had, they ended up merging the patch from the wrong
place, but the warning should be fixed. In future I'll just take the
patch myself!
Outside drm:
There are some snd changes for the HDMI audio interactions on haswell,
they've been acked for inclusion via my tree. This relies on the
wound/wait tree from Ingo which is already merged.
Major changes:
AMD finally released the dynamic power management code for all their
GPUs from r600->present day, this is great, off by default for now but
also a huge amount of code, in fact it is most of this pull request.
Since it landed there has been a lot of community testing and Alex has
sent a lot of fixes for any bugs found so far. I suspect radeon might
now be the biggest kernel driver ever :-P p.s. radeon.dpm=1 to enable
dynamic powermanagement for anyone.
New drivers:
Renesas r-car display unit.
Other highlights:
- core: GEM CMA prime support, use new w/w mutexs for TTM
reservations, cursor hotspot, doc updates
- dvo chips: chrontel 7010B support
- i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell),
Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp
support (this time for sure)
- nouveau: async buffer object deletion, context/register init
updates, kernel vp2 engine support, GF117 support, GK110 accel
support (with external nvidia ucode), context cleanups.
- exynos: memory leak fixes, Add S3C64XX SoC series support, device
tree updates, common clock framework support,
- qxl: cursor hotspot support, multi-monitor support, suspend/resume
support
- mgag200: hw cursor support, g200 mode limiting
- shmobile: prime support
- tegra: fixes mostly
I've been banging on this quite a lot due to the size of it, and it

This is the second part of OMAP DSS changes for 3.11. This part contains the
new DSS device model support.
The current OMAP panel drivers use a custom DSS bus, and there's a hard limit
of one external display block per video pipeline. In the new DSS device model
the devices/drivers are made according to the control bus of the display block,
usually platform, i2c or spi. The display blocks can also be chained so that we
can have separate drivers for setups with both external encoder and panel.
To allow the current board files, which use the old style panels, to function,
the old display drivers are left in their current state, and new ones are added
to drivers/video/omap2/displays-new/. When the board files have been converted
to use the new style panels, we can remove the old code. This is planned to
happen in v3.12.
Having to support two very different DSS device models makes the driver
somewhat confusing in some parts, and prevents us from properly cleaning up
some other parts. These cleanups will be done when the old code is removed.
The new device model is designed with CDF (Common Display Framework) in mind.
While CDF is still under work, the new DSS device model should be much more
similar to CDF's model than the old device model, which should make the
eventual conversion to CDF much easier.

Having to support two very different DSS device models makes the driver
somewhat confusing in some parts, and prevents us from properly cleaning up
some other parts. These cleanups will be done when the old code is removed.
The new device model is designed with CDF (Common Display Framework) in mind.
While CDF is still under work, the new DSS device model should be much more
similar to CDF's model than the old device model, which should make the
eventual conversion to CDF much easier.
This is the first part of OMAP DSS changes for 3.11. This part contains fixes,
cleanups and reorganizations that are not directly related to the new DSS
device model that is added in part 2, although many of the reorganizations are
made to make the part 2 possible.
There should not be any functional changes visible to the user except the few
bug fixes.
The main new internal features:
- Display (dis)connect support, which allows us to explicitly (dis)connect a
whole display pipeline
- Panel list, which allows us to operate without the specific DSS bus
- Combine omap_dss_output to omap_dss_device, so that we have one generic
"entity" for display pipeline blocks

In order to allow multiple display block in a video pipeline, we need to
give the drivers way to register themselves. For now we have
the omapdss_register_display() which is used to register panels, and
dss_register_output() which is used to register DSS encoders.
This patch makes dss_register_output() public (with the name of
omapdss_register_output), which can be used to register also external
encoders. The distinction between register_output and register_display
is that a "display" is an entity at the end of the videopipeline, and
"output" is something inside the pipeline.
The registration and naming will be made saner in the future, but the
current names and functions are kept to minimize changes during the dss
device model transition.
