d03f3f6304 drm/amd/display: fix check condition for edp power control
Per discussion with VBIOS team, the orginal check is not correct in
all cases on latest VBIOS. Additional check is needed. This change should
maintain old behaviour on older VBIOS.

65e4b49019 drm/amd/display: validate plane format on primary plane
In dce110, the plane configuration is such that plane 0
or the primary plane should be rendered with only RGB data.

This patch adds the validation to ensure that no video data

f03628232f drm/amd/display: Clear dmps off for eDP when resume.
This patch fixed secondary screen only S4 resume, eDP is unintentionally
light up due to incorrect dpms off flag.

When entering S4, dpms off flags are set to true via
set power state. During resume, eDP is light up by vbios, so the flags
should be changed to false to match the real state.
By change the flag properly, eDP is able to be turned off properly as per
OS request.

This change may affect S3/S4 Shut down resume IOIC, need to verify

71d0a89812 amdgpu/dc: Fix enum mismatch in calls to program_color_matrix()
The driver passes GRAPHICS_CSC_ADJUST_TYPE_SW of type enum
graphics_csc_adjust_type to program_color_matrix(), however the function
expects a parameter of type enum grph_color_adjust_option. Supposedly
the intention was to pass GRPH_COLOR_MATRIX_SW, which has the same value
as GRAPHICS_CSC_ADJUST_TYPE_SW, so the mismatch didn't cause any trouble.

Pass GRPH_COLOR_MATRIX_SW to program_color_matrix() instead of
GRAPHICS_CSC_ADJUST_TYPE_SW, this also fixes the following warning when
building the kernel with clang:

drivers/gpu/drm/amd/amdgpu/../display/dc/dce/dce_transform.c:1129:24:
  error: implicit conversion from enumeration type
  'enum graphics_csc_adjust_type' to different enumeration type

8f8372c7d1 drm/amd/display: Optimize regamma calculations
There are several optimizations:
1) Use predefined SRGB, don't calculate. This is the most common case.
2) Precompute HW X points at boot since they're fixed in ColModule
3) Precompute PQ - it never changes and is very CPU intensive in fixed pt.
4) Reduce number of points in ColModule to 512 (32x16) from 1024. This also
requires reducing some regions for legacy DCEs to 16 pts at most.

Performance
1) is super-fast, build_output_tf is 1-2us, down from 25000-30000.
Programming also fast since only one reg write.
2)+3) gives build_output_tf for PQ in ~100us range, down from ~80000-110000
2) + 4) results in slightly over 50% improvement. It gives an idea of the
savings when we can't use SRGB or PQ table (e.g. sdr white level > 80).

There's also a bit of refactoring: renaming some stuff that was misleading
and removing a lot of magic numbers that novices might not be able to
understand where they come from and what they mean.

33fd17d912 drm/amd/display: fix cursor related Pstate hang
Move cursor programming to inside the OTG_MASTER_UPDATE_LOCK

If graphics plane go from 1 pipe to hsplit, the cursor updates
after mpc programming and unlock. Which means there is a window
of time where cursor is enabled on the wrong pipe if it's on
the right side of the screen (i.e. case where cursor need to
move from pipe 0 to pipe 3 post split). This will cause pstate hang.

Solution is to program the cursor while still locked.

8aa111e34d drm/amd/display/dc/dce110/dce110_mem_input_v: use swap macro in program_size_and_rotation
Make use of the swap macro instead of _manually_ swapping values
and remove unnecessary variable swap.

This makes the code easier to read and maintain.

This code was detected with the help of Coccinelle.
