2021-06-08drm/amd/display: Refactor visual confirmWyatt Wood
[Why + How] Visual confirm has no asic-specific logic, so we can refactor and unify these functions that are currently spread out across multiple dcn files. Add a new hw sequencer interface update_visual_confirm_color, and a new mpc function pointer set_bg_color. This will allow visual confirm to updated independently of MPCC blending updates. v2: squash in DCN3.1 fixes Signed-off-by: Wyatt Wood <wyatt.wood@amd.com> Reviewed-by: Aric Cyr <Aric.Cyr@amd.com> Acked-by: Stylon Wang <stylon.wang@amd.com> Tested-by: Daniel Wheeler <daniel.wheeler@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>

[why] DSCCLK validation is not necessary because DSCCLK is derrived from DISPCLK, therefore if DISPCLK validation passes, DSCCLK is valid, too.

2021-06-08drm/amd/display: delay 100ms before restart after failing to read CP_IRQWenjing Liu
[why] Some DPRX will issue CP_IRQ when user disconnects a display that has been authenticated. Since display is being disconnecting dpcd read will fail. This will cause us to attempt HDCP retry on disconnection. We are adding a 100ms delay before retry. So we will only start retry if within 100ms there is no disconnection call to HDCP module.
