Calling force_performance_level() from set_power_state()
doesn't work on some asics because the current power
state pointer has not been properly updated at that point.
Move the calls to force_performance_level() out of the
asic specific set_power_state() functions and into
the main power state sequence.

The OUTPUT_ENABLE action jumps past the point in the coder where
the data_offset is set on certain rs780 cards. This worked
previously because the OUTPUT_ENABLE action is always called
immediately after the ENABLE action so the data_offset remained
set. In 6f8bbaf568
(drm/radeon/atom: initialize more atom interpretor elements to 0),
we explictly reset data_offset to 0 between atom calls which then
caused this to fail. The fix is to just skip calling the
OUTPUT_ENABLE action on the problematic chipsets. The ENABLE
action does the same thing and more. Ultimately, we could
probably drop the OUTPUT_ENABLE action all together on DCE3
asics.

Certain r6xx boards use the same power state for both UVD

at the moment, there was no callback installed for setting
the UVD clocks, however, on systems that use the same power
state, this leads to a NULL pointer dereference. Fill
in a stubbed out implementation for now to avoid the crash.

The problem here is that "unsigned i" is always greater than or equal to
zero. These loops mostly have a second check for "(i == 0)" so only the
last two are actually buggy. The rest is just cleanup.
Bug 1: kv_force_dpm_highest() doesn't have an "(i == 0)" check so it's
a potential forever loop.
Bug 2: In kv_get_sleep_divider_id_from_clock() there is a typo and the
test is reversed "<=" vs ">" so we never enter the loop. That means
normally we return KV_MAX_DEEPSLEEP_DIVIDER_ID (5). The return value
from here is saved in ->DeepSleepDivId and I wasn't able to determine
how that is used. This is a static checker fix and I have not tested

When transitioning away from vgacon the system tries to save the

off to fbcon (or whatever comes afterwards).

Author: Alex Williamson <alex.williamson@redhat.com>

i915: Update VGA arbiter support for newer devices
caused i915 to disable VGA memory decode for the IGD when i915 is
initializing. Unfortunately that happens before the vgacon->fbcon
handoff so vgacon_save_screen() will read out all ones from the
VGA memory.
After the handoff fbcon will inherit the bogus state from vgacon,
and pre-fills the fb with matching contents. The end result is
a white rectangle in the top left corner of the screen, the size
of which matches the now inactive VGA console.
To remedy the situation delay the disabling of VGA memory until
the vgacon->fbcon handoff has happened.
Also rename i915_enable_vga to i915_enable_vga_mem to make
the relationship between these functions clearer.

ACPI has _BCM and _BQC methods to set and query the backlight
brightness, respectively. The ACPI opregion has variables BCLP and CBLV
to hold the requested and current backlight brightness, respectively.
The BCLP variable has range 0..255 while the others have range
0..100. This means the _BCM method has to scale the brightness for BCLP,
and the gfx driver has to scale the requested value back for CBLV. If
the _BQC method uses the CBLV variable (apparently some implementations
do, some don't) for current backlight level reporting, there's room for
rounding errors.
Use DIV_ROUND_UP for scaling back to CBLV to get back to the same values
that were passed to _BCM, presuming the _BCM simply uses bclp = (in *
255) / 100 for scaling to BCLP.

This blew up while running kms_flip/flip-vs-panning-vs-hang-interruptible
on one of my older machines.
Unfortunately (despite the proper lockdep annotations for
flush_workqueue) lockdep still doesn't detect this correctly, so we
need to rely on chance to discover these bugs.
Apply the usual bugfix and schedule the reset work on the system
workqueue to keep our own driver workqueue free of any modeset lock
grabbing.
Note that this is not a terribly serious regression since before the
offending commit we'd simply have stalled userspace forever due to
failing to abort all outstanding pageflips.

Whilst running the shrinker, we need to hold a reference as we unbind
the objects, or else we may end up waiting for and retiring requests,
which in turn may result in this object being freed.
This is very similar to the eviction code which also has to be very
careful to keep a reference to its objects as it retires and unbinds
them.
Another similarity, that Ben pointed out, is that as we may call
retire-requests, the unbound_list is outside of our control. We must
only process a single element of that list at a time, that is we can not
rely on the "safe" next pointer being valid after a call to
i915_vma_unbind().

Summary:
- Consider fallback option to gem allocation fail
. try to allocate physically non-contiguous memory
if iommu is supported when physically contiguous memory allocation
failed.
- Add runtime pm support to g2d driver
- Add device tree support
. add device tree support to rotator driver, make fimd driver get
signal polarities from device tree.
- some fixups
. correct pixel format setting to fimd driver, and consider pixel
format checking to a particular window layer.
- some cleanups
. replace fb_videomode with videomode.
. remove non-DT support

exynos_drm_connector.c now uses videomode helper API. Hence select
VIDEOMODE_HELPERS at DRM_EXYNOS level itself instead of at
DRM_EXYNOS_FIMD to avoid the following compilation error when FIMD
is not selected (introduced by commit cf796235a6 "drm/exynos: fimd:
replace struct fb_videomode with videomode"):
drivers/built-in.o: In function `exynos_drm_connector_get_modes':
drivers/gpu/drm/exynos/exynos_drm_connector.c:86:
undefined reference to `drm_display_mode_from_videomode'

Since commit 383ffda2fa ("ARM: EXYNOS: no more support non-DT
for EXYNOS SoCs"), Exynos platform is DT only. Hence remove
all the conditional macros and make the driver DT only.
