drm/amd/display: Enabling eDP no power sequencing with DAL feature mask
[Why]
Sometimes, DP receiver chip power-controlled externally by an
Embedded Controller could be treated and used as eDP,
if it drives mobile display. In this case,
we shouldn't be doing power-sequencing, hence we can skip
waiting for T7-ready and T9-ready."
[How]
Added a feature mask to enable eDP no power sequencing feature.
To enable this, set 0x10 flag in amdgpu.dcfeaturemask on
Linux command line.
