Bug Description

[SRU Justification]

[Impact]

Multiple issues in DP alt mode, PSR-SU(Panel Self Refresh–Selective Update), and HDMI signal integrity.

[Fix]

Upstream commit b0f995cd61cd ("amdgpu: update DMCUB firmware for DCN 3.1.6") that updates binary firmware.

[Test Case]

Can only be verified with dedicated equipment from vendor.

[Where problems could occur]

Binary firmware, everything can go wrong.

[Other Info]

Already in korg upstream, included in Lunar, too. Only Jammy and Kinetic will be nominated for fix.

========== original bug report ==========

Some fixes for DP alt mode and PSR-SU(Panel Self Refresh–Selective Update), and also improve HDMI signal integrity. This FW would be tuning PHY of HDMI to enhance signal integrity in eye diagram to reach HDMI spec(2.0/1.4b), and also avoid any risk on monitor with multiple resolutions over HDMI output.
