[Why] When calculating recout width for an MPO plane on a mode that's using ODM combine, driver can calculate a negative value, resulting in a crash. [How] For negative widths, use zero such that validation will prune the configuration correctly and disallow MPO. Signed-off-by:

[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:

[why] DSCCLK validation is not necessary because DSCCLK is derrived from DISPCLK, therefore if DISPCLK validation passes, DSCCLK is valid, too. Doing DSCLK validation in addition to DISPCLK leads to modes being wrongly rejected when DSCCLK was incorrectly set outside of DML. [how] Remove DSCCLK validation because it's implicitly validated under DISPCLK Signed-off-by:

[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.
