From a49d1acbbe63af9b5f4f331eecbee454efffd8af Mon Sep 17 00:00:00 2001

Subject: [PATCH 1133/2940] drm/amd/display: fix eDP fast bootup for pre-raven
asic
[Why]
For fastboot, Bios will light up eDP before SW driver is loaded. SW
driver will check if eDP is lit by bios through reading the
BIOS_SCRATCH_3 register. If lit, SW driver will not power down eDP
power and phy to save time.
Definition of BIOS_SCRATCH_3 are missing for pre-raven asic. This
causes eDP fast boot to not work property. For some eDP panels, even
if dp tx sends NoVideoStream_flag =1 and dpcd 0x600=2, eDP rx may not
handle properly. This may cause a short flash on screen.
[How] Add definition of BIOS_SCRATCH_3 for all asic
