[ Upstream commit 3601d620f22e37740cf73f8278eabf9f2aa19eb7 ]

[Why]
For HDR mode, we get total 512 tf_point and after switching to SDR mode
we actually get 400 tf_point and the rest of points(401~512) still use
dirty value from HDR mode. We should limit the rest of the points to max
value.

[How]
Limit the value when coordinates_x.x &gt; 1, just like what we do in
translate_from_linear_space for other re-gamma build paths.

Rename dp/ to display/ to account for additional display-related
helpers, such as HDMI. Update all related include statements. No
functional changes.

Various drivers, such as i915 and amdgpu, use similar naming scheme
by putting code for video-output standards into a local display/

<content type='text'>
[why]
creating a generic helper for AMD specific PSR-SU sink validation.
Moving the function to the power module to reference it across all
OS.

[how]
- drop PSRSU specific sink validation helper and move to power
  module by reading PSR version and other PSR caps
- call the new helper from linux DM (amdgpu_dm_psr)

<title>drm/amd/display: Fix inconsistent timestamp type</title>

<id>19a2e1e36a2b14d7549a6d9584be131f4286f757</id>
<content type='text'>
[WHY]
An unsigned int timestamp variable is assigned with an unsigned
long long value. Also, the assignment directly converts the
tick value to us without using built-in get elapsed time function.

[HOW]
Cast the assigned value correctly and also use built-in function
to get the timestamp in the unit we want.
