OMAPDSS's RFBI encoder driver has not been working for some time. The
Nokia N800 is the only board in the mainline that uses RFBI, but it has
never been fully functional.
The RFBI driver needs to be updated to the new panel model, but as
the driver is rather unmaintained and there's no way to test the
changes, let's mark the driver as broken.

LCDC IP has a clock divider to adjust pixel clock, this limits pixel
clock range to fck/255 - fck/2(fck - rate of input clock to LCDC IP).
In the case of AM335x, where this IP is present, default fck is not
sufficient to provide normal pixel clock rates, hence rendering this
driver unusable on AM335x.
If input clock too is configurable, allowable range of pixel clock
would increase. Here initially it is checked whether with present fck,
divider in IP could be configured to obtain required rate, if not,
fck is adjusted. This makes it usable on AM335x.
Note:
Another solution would be to model an inherited basic clock divider of
CCF, an advantage would be a better possible resolution for pixel clk.
And trying to instantiate a CCF clock would mean that to be consistent,
3 bits being turned on to enable clocks of LCDC IP would have to be
modeled as gate clocks. Now that would bring in a total of 4 clocks,
including necessity to create a new inherited divider clock, and that
mean a branch of clock tree would be present in LCDC driver. This
would add complexity to LCDC driver bringing in considerable amount
of clock handling code, and this would not bring in much advantage
for existing use cases other than providing a higher resolution of
pixel clock. And existing use cases work without relying on clock
modeling. Another fact is that out of the two platform's using this
driver DaVinci is not yet converted to CCF. In future if higher
resolution of pixel clock is required, and probably after DaVinci is
CCF'ed, modeling clock nodes inside driver may be considered.

takes a copy of the infoframe from the ip_data, and then goes on
initializing that copy. The initialized data is never copied back to the
ip_data container, thus the infoframe in ip_data is left always zero.
Afaik, this doesn't really cause any issues in the current mainline, as
we don't use the advanced features offered by the AVI infoframe.

fbdev provides framebuffer hotplugging, hence, we need to allow fbcon to
unbind from framebuffers. Unfortunately, fbcon_fb_unbind() cannot unbind
from the last framebuffer, unless console-unbinding is supported.
Fixing fbcon_unbind() to return 0 caused some horrible NULL-derefs in the
VT layer and I couldn't figure out why. Hence, lets just require
console-unbinding so fbdev hotplugging works with fbcon.

Both information is used by remove_conflicting_framebuffers() to remove a

for VGA/vesa/EFI framebuffers, but is also of great use for all other

If we create proper platform-devices in x86 boot-code, we can use simplefb
for VBE or EFI framebuffers, too. However, there is normally no OF support
so we introduce a platform_data object so x86 boot-code can pass the
parameters via plain old platform-data.
This also removes the OF dependency as it is not needed. The headers

The IM pins of the HX8357 controller are used to define the interface
used to feed pixel stream to the LCD panel.
Most of the time, these pins are directly routed to either the ground or
the VCC to set their values.
Remove the need to assign GPIOs to these pins when we are in such a case.

For a combination of 18bit LCD data bus width and a color
mode of 32bpp, the driver was setting the color mapping to
rgb666, which is wrong, as the color in memory realy has an
rgb888 layout.
This patch also removes the setting of flag CTRL_DF24 that
makes the driver dimiss the upper 2 bits when handling 32/24bpp
colors in a diplay with 18bit data bus width. This flag made
true color images display wrong in such configurations.
Finally, the color mapping rgb666 has also been removed as nobody
is using it and high level applications like Qt5 cannot work
with it either.

connector-analog-tv.c uses omap_dss_pal_timings, defined in omapdss's
venc.c, for default timings. omap_dss_pal_timings only exists when VENC
is enabled in the kernel config, so disabling VENC breaks
omap_dss_pal_timings connector-analog-tv compilation.
Instead of adding dependency to VENC, add internal default timings to
the connector driver, because the connector driver should not depend on
VENC, and it can be used with any other analog TV encoder.

Remove HV_DRV_VERSION, it has no meaning for upstream drivers.
Initially it was supposed to show the "Linux Integration Services"
version, now it is not in sync anymore with the out-of-tree drivers
available from the MSFT website.
The only place where a version string is still required is the KVP
command "IntegrationServicesVersion" which is handled by
tools/hv/hv_kvp_daemon.c. To satisfy such KVP request from the host pass
the current string to the daemon during KVP userland registration.

The device-tree enablement for max8925 has several problems, but besides
the bindings being wrong (and not having seen review) there's also some
bad coding practices on how to fill in the platform_data from device tree.
I came across this since it causes a warning when compiling
mmp2_defconfig, and instead of doing the minimal fix to silence the
warning, I restructured the code a bit.
This silences the warning:
drivers/video/backlight/max8925_bl.c: In function 'max8925_backlight_probe':
drivers/video/backlight/max8925_bl.c:177:3: warning: statement with no effect [-Wunused-value]
Note that the bindings themselves need to be revisited too, but that will
affect more than just the backlight driver and is best done separately;
this just fixes the bad code for the backlight driver.

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
seems to okay on everything I've tested it on."

Pull workqueue changes from Tejun Heo:
"Surprisingly, Lai and I didn't break too many things implementing
custom pools and stuff last time around and there aren't any follow-up
changes necessary at this point.
The only change in this pull request is Viresh's patches to make some
per-cpu workqueues to behave as unbound workqueues dependent on a boot
param whose default can be configured via a config option. This leads
to higher processing overhead / lower bandwidth as more work items are
bounced across CPUs; however, it can lead to noticeable powersave in
certain configurations - ~10% w/ idlish constant workload on a
big.LITTLE configuration according to Viresh.
This is because per-cpu workqueues interfere with how the scheduler
perceives whether or not each CPU is idle by forcing pinned tasks on
them, which makes the scheduler's power-aware scheduling decisions
less effective.
Its effectiveness is likely less pronounced on homogenous
configurations and this type of optimization can probably be made
automatic; however, the changes are pretty minimal and the affected
workqueues are clearly marked, so it's an easy gain for some
configurations for the time being with pretty unintrusive changes."

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.

OMAP display subsystem changes for 3.11 (part 2/2)
This is the second part of OMAP DSS changes for 3.11. This part contains the

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

Several drivers need font support independent of CONFIG_VT, cfr. commit
9cbce8d7e1dae0744ca4f68d62aa7de18196b6f4, "console/font: Refactor font
support code selection logic").
Hence move the fonts and their support logic from drivers/video/console/ to
its own library directory lib/fonts/.
This also allows to limit processing of drivers/video/console/Makefile to
CONFIG_VT=y again.

drm_get_connector_name now returns a const value, which causes the following
compilation warning:
drivers/gpu/drm/drm_fb_helper.c: In function ‘drm_fb_helper_parse_command_line’:
drivers/gpu/drm/drm_fb_helper.c:127:3: warning: passing argument 1 of ‘fb_get_options’ discards ‘const’ qualifier from pointer target type [enabled by default]
In file included from drivers/gpu/drm/drm_fb_helper.c:35:0:
include/linux/fb.h:627:12: note: expected ‘char *’ but argument is of type ‘const char *’
As fb_get_options uses its name argument as read only, make it const. This
fixes the aforementioned compilation warning.

Pci core has been saved pm cap register offset by pdev->pm_cap in pci_pm_init()
