drm/amd/display: Use drm_connector in create_validate_stream_for_sink

2023-10-03T19:41:45+00:00

[WHAT] Again, we need to use this function for writeback connectors, which are not of type amdgpu_dm_connector. Use the common base drm_connector instead. Reviewed-by: Alex Hung Signed-off-by: Harry Wentland Signed-off-by: Alex Hung Signed-off-by: Alex Deucher

drm/amd/display: Add polling method to handle MST reply packet

2023-07-18T15:12:50+00:00

[Why] Specific TBT4 dock doesn't send out short HPD to notify source that IRQ event DOWN_REP_MSG_RDY is set. Which violates the spec and cause source can't send out streams to mst sinks. [How] To cover this misbehavior, add an additional polling method to detect DOWN_REP_MSG_RDY is set. HPD driven handling method is still kept. Just hook up our handler to drm mgr->cbs->poll_hpd_irq().
