0febd3bccf Omapdss driver changes for the 3.7 merge window.
Notable changes:
 
 * Basic writeback support for DISPC level. Writeback is not yet usable, though,
   as we need higher level code to actually expose the writeback feature to
   userspace.
 * Rewriting the omapdss output drivers. We're trying to remove the hard links
   between the omapdss and the panels, and this rewrite work moves us closer to
   that goal.
 * Cleanup and restructuring patches that have been made while working on device
   tree support for omapdss. Device tree support is still some way ahead, but
   these patches are good cleanups in themselves.
 * Basic OMAP5 DSS support for DPI and DSI outputs.
 * Workaround for the problem that GFX overlay's fifo is too small for high
   resolution scenarios, causing underflows.
 * Cleanups that remove dependencies to omap platform code.

Adam Jackson added the quirk `EDID_QUIRK_FORCE_REDUCED_BLANKING` which
is also needed for this ASUS monitor.

All log files and output from `xrandr` is included in the referenced
Bugzilla report #17629.

Please note that this monitor only has a VGA (D-Sub) connector [1].

4a68a74ba0 gma500: Consider CRTC initially active.
[this one ideally should make 3.6 - it fixes the very annoying mode setting bug]

This causes the pipe to be forced off prior to initial mode set, which
roughly mirrors the behavior of the i915 driver.  It fixes initial mode
setting on my Intel DN2800MT (Cedarview) board.  Without it, mode
setting triggers an out-of-range error from the monitor for most modes,
but only on initial configuration (i.e. they can be configured
successfully from userspace after that).

radeon_ring_restore is freeing the memory for the saved
ring data. We need to remember that, otherwise we try to
restore the ring data again on the next try. Additional
to that it shouldn't try the reset infinitely if we have
saved ring data.

0ceb996c9e drm/radeon: rework panel mode setup
Adjust the panel mode setup to match the behavior
of the vbios.  Rather than checking for specific
bridge chip ids, just check the eDP configuration register.
This saves extra aux transactions and works across
DP bridge chips without requiring additional per chip

c205b232a6 drm/radeon/atom: powergating fixes for DCE6
Power gating is per crtc pair, but the powergating registers
should be called individually.  The hw handles power up/down
properly.  The pair is powered up if either crtc in the pair
is powered up and the pair is not powered down until both
crtcs in the pair are powered down.  This simplifies
programming and should save additional power as the previous
code never actually power gated the crtc pair.

8d1af57ae3 drm/radeon/atom: rework DIG modesetting on DCE3+
The ordering is important and the current drm code
wasn't cutting it for modern DIG encoders.  We need
to have information about crtc before setting up
the encoders so I've shifted the ordering a bit.
Probably we'll need a full rework akin to danvet's
recent intel patchs.  This patch fixes numerous
issues with DP bridge chips and makes link training
much more reliable.

523885dec1 drm/radeon: add proper checking of RESOLVE_BOX command for r600-r700
Checking of the second colorbuffer was skipped on r700, because
CB_TARGET_MASK was 0xf. With r600, CB_TARGET_MASK is changed to 0xff,
so we must set the number of samples of the second colorbuffer to 1 in order
to pass the CS checker.
The DRM version is bumped, because RESOLVE_BOX is always rejected without this
fix on r600.

On some Fermi chipsets (NVCE particularly) PCOPY1 doesn't exist.  And if
what I've seen on Kepler is true of Fermi too, chipsets of the same type
can have different PCOPY units available.

This should fix a v3.5 regression reported by a number of people effecting
suspend/resume on NVC8/NVCE chipsets.

This board is incorrectly detected as having an LVDS connector,
resulting in the VGA output (the only available output on the board)
showing the console only in the top-left 1024x768 pixels, and an extra
LVDS connector appearing in X.

It's a desktop Mini-ITX board using an Atom D525 CPU with an NM10
chipset.

I've had this board for about a year, but this is the first time I
noticed the issue because I've been running it headless for most of its

f5869a8308 drm: stop vmgfx driver explosion
If you do a page flip with no flags set then event is NULL. If event is
NULL then the vmw_gfx driver likes to go digging into NULL and extracts
NULL->base.file_priv.

On a modern kernel with NULL mapping protection it's just another oops,
without it there are some "intriguing" possibilities.

What it should do is an open question but that for the driver owners to
sort out.

8f057d7bca gpu/mfd/usb: Fix USB randconfig problems
Fix config warning:

warning: ( ... && DRM_USB) selects USB which has unmet direct dependencies
(USB_SUPPORT && USB_ARCH_HAS_HCD)

and build error:
ERROR: "usb_speed_string" [drivers/usb/core/usbcore.ko] undefined!

by adding the missing dependency on USB_ARCH_HAS_HCD to DRM_UDL and DRM_USB.

This exposes:
drivers/video/Kconfig:36:error: recursive dependency detected!
drivers/video/Kconfig:36:       symbol FB is selected by DRM_KMS_HELPER
drivers/gpu/drm/Kconfig:28:     symbol DRM_KMS_HELPER is selected by DRM_UDL
drivers/gpu/drm/udl/Kconfig:1:  symbol DRM_UDL depends on USB_ARCH_HAS_HCD

drivers/video/Kconfig:373:      symbol FB_CYBER2000 depends on FB

which is due to drivers/usb/Kconfig:
config USB_ARCH_HAS_OHCI
	...
	default y if ARCH_PNX4008 && I2C

Fix by dropping I2C from the above dependency; logic is that this is not a
platform dependency but a configuration dependency: the _architecture_ still
supports USB even is I2C is not selected.

This exposes:
drivers/video/Kconfig:36:error: recursive dependency detected!
drivers/video/Kconfig:36:       symbol FB is selected by DRM_KMS_HELPER
drivers/gpu/drm/Kconfig:28:     symbol DRM_KMS_HELPER is selected by DRM_UDL

drivers/mfd/Kconfig:396:        symbol MFD_TC6393XB depends on GPIOLIB
drivers/gpio/Kconfig:35:        symbol GPIOLIB is selected by FB_VIA
drivers/video/Kconfig:1560:     symbol FB_VIA depends on FB

which can be fixed by having MFD_TC6393XB select GPIOLIB instead of depending on
it.

1ee9ae3244 drm/i915: use hsw rps tuning values everywhere on gen6+
James Bottomley reported [1] a massive power regression, due to the
enabling of semaphores by default in 3.5. A workaround for him is to
again disable semaphores. And indeed, his system has a very hard time
to enter rc6 with semaphores enabled.

Ben Widawsky run around with a kill-a-watt a lot and noticed:
- There are indeed a few rare systems that seem to have a hard time
  entering rc6 when desktop-idle.
- One machine, The Indestructible Toshiba regressed in this behaviour
  between 3.5 and 3.6 in a merge commit! So rc6 behaviour with the
  current setting seems to be highly timing dependent and not robust
  at all.
- The behaviour James reported wrt semaphores seems to be a freak
  timing thing that only happens on his specific machine, confirming
  that enabling semaphores shouldn't reduce rc6 residency.

Now furthermore the Google ChromeOS guys reported [2] a while ago that
at least on some machines a simply a blinking cursor can keep the gpu
turbo at the highest frequency. This is because the current rps limits
used on snb/ivb are highly asymmetric.

On the theory that gpu turbo and rc6 tuning values are related, we've
tried whether the much saner looking (since much less asymmetric) rps
tuning values used for hsw would also help entering rc6 more robustly.

And it seems to mostly work, and we don't really have the resources to
through-roughly tune things in any better way: The values from the
ChromeOS ppl seem to fare a bit worse for James' machine, so I guess
we better stick with something vpg (the gpu hw/windows group)
provided, hoping that they've done their jobs.

fcdeefe4df drm/radeon: fix checking of MSAA renderbuffers on r600-r700
The MSAA checking was mostly unimplemented on r600-r700. The userspace
submits GPU commands and the kernel driver computes how much memory
the GPU will access and checks if it's all within buffer bounds the
userspace allocated. This patch fixes the computations of the size of
MSAA surfaces in memory.

Otherwise we still have another gmbus regression (patches are awaiting
tested-bys) and there's something odd going with some rare systems not
entering rc6 often enough (and hence blowing through too much power).  It
seems to be a timing-related issue and can be mitigated by frobbing the
magic tuning parameters. We're still working on that one. Also, we still
have some fallout from the hw context support, but you can only hit that
with mesa master."
