drm/dsc: fix drm_edp_dsc_sink_output_bpp() DPCD high byte usage

2023-04-24T19:40:40Z

The operator precedence between << and & is wrong, leading to the high byte being completely ignored. For example, with the 6.4 format, 32 becomes 0 and 24 becomes 8. Fix it, and remove the slightly confusing and unnecessary DP_DSC_MAX_BITS_PER_PIXEL_HI_SHIFT macro while at it.

drm/display/dp_mst: Handle old/new payload states in drm_dp_remove_payload()

2023-02-13T19:37:29Z

Atm, drm_dp_remove_payload() uses the same payload state to both get the vc_start_slot required for the payload removal DPCD message and to deduct time_slots from vc_start_slot of all payloads after the one being removed. The above isn't always correct, as vc_start_slot must be the up-to-date version contained in the new payload state, but time_slots must be the one used when the payload was previously added, contained in the old payload state. The new payload's time_slots can change vs. the old one if the current atomic commit changes the corresponding mode. This patch let's drivers pass the old and new payload states to drm_dp_remove_payload(), but keeps these the same for now in all drivers not to change the behavior. A follow-up i915 patch will pass in that driver the correct old and new states to the function.
