drm/amd/display: get dprefclk ss info from integration info table

2023-12-19T20:22:59+00:00

[why & how]
we have two SSC_En:
we get ssc_info from dce_info for MPLL_SSC_EN.
we used to call VBIOS cmdtbl's smu_info's SS persentage for DPRECLK SS info,
is used for DP AUDIO and VBIOS' smu_info table was from systemIntegrationInfoTable.

since dcn35 VBIOS removed smu_info, driver need to use integrationInfotable directly.

drm/amd/display: disable FPO and SubVP for older DMUB versions on DCN32x

2023-12-19T20:20:57+00:00

There have recently been changes that break backwards compatibility,
that were introduced into DMUB firmware (for DCN32x) concerning FPO and
SubVP. So, since those are just power optimization features, we can just
disable them unless the user is using a new enough version of DMUB
firmware.

drm/amd/display: Restore guard against default backlight value < 1 nit

2023-12-11T17:41:05+00:00

Mark reports that brightness is not restored after Xorg dpms screen blank.

This behavior was introduced by commit d9e865826c20 ("drm/amd/display:
Simplify brightness initialization") which dropped the cached backlight
value in display code, but also removed code for when the default value
read back was less than 1 nit.

Restore this code so that the backlight brightness is restored to the
correct default value in this circumstance.

drm/amd/display: fix hw rotated modes when PSR-SU is enabled

2023-12-11T17:41:05+00:00

We currently don't support dirty rectangles on hardware rotated modes.
So, if a user is using hardware rotated modes with PSR-SU enabled,
use PSR-SU FFU for all rotated planes (including cursor planes).
