drm/amd/display: add a func to disable accelerated mode

2021-03-24T03:33:36Z

[Why] When driver disabled, we driver force the YCbCr420 to RGB, which means some register will be changed, such as RDPCS_PHY_DP_MPLLB_TX_CLK_DIV changed from 1 to 0 When driver re-enabled, OS will Set Mode YCbCr420 again, which means the register RDPCS_PHY_DP_MPLLB_TX_CLK_DIV should to be 1 again, but dmub fw can’t update the register to 1 due to the mpll is not off [How] Adds an interface to disable accelerated mode bit, which allows DM to decide to call during driver disable/unload scenarios.

drm/amd/display: fix eDP fast bootup for pre-raven asic

2019-01-25T21:15:36Z

[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.
