drm/radeon: add support for 3d perf states on older asics
Certain older rv770 asics have both a performance and
a 3D performance state rather than just multiple performance
levels in the state power state. The current code would
select the performance state rather than the 3D performance
state when the "performance" profile was selected. This change
switches to the "balanced" profile by default which ends up being
the internal performance profile. When the user selects the
"performance" profile, it selects the internal 3D performance
state so the user can select the higher performance modes.
For most asics this changes nothing. For certain rv770 asics
with static performance and 3D performance states, this allows
you to select between then using by selecting the "balanced"
and "performance" dpm profiles.

Merge branch 'exynos-drm-next' of git://git./linux/kernel/git/daeinki/drm-exynos into drm-next
Feature summary:
Add S3C64XX SoC series support - S3C64XX SoC series are previous version
chips of Exynos SoC series. With this patch set, KMS driver of Exynos drm
supports those chips also.
Update device tree support - This patch set corrects compatible strings,
and adds Exynos5420 SoC support for hdmi subsystem.
Consider CCF (Common Clock Framework) support - With reference to CCF
support, it uses clock_prepare_enable/clock_disable_unprepare instead of
clk_enable/clk_disable for hdmi subsystem.
Big cleanups - This patch just removes unnecessary all debug logs.

ARM: dts: change compatible strings for EXYNOS5250 hdmi subsystem
This patch renames the combatible strings for hdmi, mixer, ddc
and hdmiphy. It follows the convention of using compatible string
which represent the SoC in which the IP was added for the first
time.

drm/exynos: fix interlace resolutions for exynos5420
Modified code for calculating hdmi IP register values from drm timing
values. The modification is based on the inputs from hw team and specifically
proposed for 1440x576i and 1440x480i. But same changes holds good for other
interlaced resolutions also.

vm_mmap function returns unsigned long so addr type should be unsigned long.
a pointer or address variable is required to use unsigned long or uint64_t
type for 64bits address support.
So this patch makes sure that addr has unsigned long type and also
exynos_drm_gem_mmap_ioctl returns correct error type.

This patch renames check_timing to check_mode and removes the
unnecessary conversion of drm_display_mode to/from fb_videomode in
the hdmi driver.
v4:
1) Changed the commit message to add information related to renaming
the callbacks to check_mode.
2) Changed debug message to print 1/0 for interlace mode.
v3:
1) Replaced check_timing callbacks with check_mode.
2) Change the type of second parameter of check_mode callback from void
pointer paramenter to struct drm_display_mode pointer.
v2:
1) Removed convert_to_video_timing().
2) Corrected DRM_DEBUG_KMS to print the resolution properly.
