drm/nv84/disp: Fix HDMI audio regression

Code refactoring in commit 8e9e3d2deacc460fbb8a4691140318f6e85e6891
(drm/nv84/disp: move hdmi control into core) disabled HDMI audio on my
nv84 by removing too much old code without adding it in the new one.
This patch adds the missing code within the new code layout resulting in
HDMI audio working again.
It should work on any HDMI head, but due to lacking ahrdware I could
only test the (1st) one.
It also might be possible that similar code is needed for nva3, which I
can't test.

drm/shmobile: Fix race condition between page flip request and handler

The page flip handler stores the page flip event pointer and then calls
drm_vblank_get() to enable the vblank interrupt. Due to the vblank off
delay, the vblank interrupt can be enabled in the hardware at that
point, even if the vblank reference count is equal to 0. If a vblank
interrupt is triggered between storing the event pointer and calling
drm_vblank_get(), the page flip completion handler will process the
event and call drm_vblank_put() with a reference count equal to 0. This
will result in a BUG_ON.

Fix the race condition by calling drm_vblank_get() before storing the
event pointer.

drm/tilcdc: use only a single module device table

The tilcdc driver fails to be built as a module because of extraneous

drivers/gpu/drm/tilcdc/tilcdc_slave.o:(.data+0x54): multiple definition of `__mod_of_device_table'

Merge branch 'gma500-fixes' of git://github.com/patjak/drm-gma500 into drm-next

Two fixes for gma500. First one from Anisse allows us to handle ASLE irqs even
when BIOS doesn't trigger a pipe event irq. The second one allows dual head
setups to have a big shared framebuffer.

  drm/gma500: fix backlight hotkeys behaviour on netbooks

drm/gma500: Increase max resolution for mode setting

By having a higher max resolution we can now set up a virtual
framebuffer that spans several monitors. 4096 should be ok since we're
gen 3 or higher and should be enough for most dual head setups.

drm/gma500: fix backlight hotkeys behaviour on netbooks

Backlight hotkeys weren't working before on certain cedartrail laptops.

The source of this problem is that the hotkeys' ASLE opregion interrupts
were simply ignored. Driver seemed to expect the interrupt to be
associated with a pipe, but it wasn't.

Accepting the ASLE interrupt without an associated pipe event flag fixes
the issue, the backlight code is called when needed, making the
brightness keys work properly.

[patrik: This patch affects irq handling on any netbook with opregion support]

drm/radeon: switch audio handling to use callbacks

Register audio callbacks for asic where we support
audio.  Cleans up the code and makes it easier to
add support for newer asics.

drm/tegra: Changes for v3.10-rc1

The bulk of this pull-request is the host1x series that has been in the
works for a few months. The current implementation looks good and has
been tested by several independent parties. So far no issues have been
found. To be on the safe side, the new Tegra-specific DRM IOCTLs depend
on staging in order to give some amount of flexibility to change them
just in case. The plan is to remove that dependency once more userspace
exists to verify the adequacy of the IOCTLs.

Currently only the 2D engine is supported, but patches are in the works
to enable 3D support on top of this framework as well. Various bits of
open-source userspace exist to test the 2D and 3D support[0]. This is
still a bit immature but it allows to verify that the kernel interfaces
work properly.

To round things off there are two smaller cleanup patches, one of them
adding a new pixel format and the other removing a redundent Kconfig
dependency.
