2023-02-28drm/amd/display: merge dc_link.h into dc.h and dc_types.hWenjing Liu
[why] Remove the need to include dc_link.h separately. dc.h should contain everything needed on DM side. [How] Merge dc_link.h into dc.h and dc_types.h so DM only needs to include dc.h to use all link public functions.

2022-06-07drm/amd/display: Add PSR-SU-RC support in DCDavid Zhang
[Why] PSR-SU Rate Control - or PSR-SU-RC - enables PSR-SU panels to work with variable refresh rate to allow for more power savings. Lowering the refresh rate can increase PSR residency by expanding the eDP main link shut down duration. It can also lower panel power consumption. There is a complication with PSR, since the eDP main link can be shut down. Therefore, the timing controller (TCON) on the eDP sink nees to be able to scan out its remote buffer independent of the main link. To allow the eDP source to specify the sink's refresh rate while the link is off, vendor-specific DPCD registers are used. This allows the eDP source to then "Rate Control" the panel during PSR active. [How] Add DC support to communicate with PSR-SU-RC supported eDP sinks. The sink will need to know the desired VTotal during PSR active. This change only adds support to DC, support in amdgpu_dm is still pending to enable this fully.
