drm/amd/display: Add DP audio BW validation [Why] Timings with small HBlank (such as CVT RBv2) can result in insufficient HBlank bandwidth for audio SDP transmission when DSC is active. This will cause some higher bandwidth audio modes to fail. The combination of CVT RBv2 timings + DSC can commonly be encountered in MST scenarios. [How] Add DP audio bandwidth validation for 8b/10b MST and 128b/132b SST/MST cases and filter out modes that cannot be supported with the current timing config.

drm/amd/display: Disable audio stream only if it's currently enabled [Why] Previously there were 2 consecutive calls being made to disable audio stream. The first one disabled the audio stream, and the second one went through and also tried to disable the audio stream causing BACO entry issues due to the ASIC appearing busy. [How] 1. Add a status field to the audio struct which stores enabled/disabled info 2. In the calls to enable/disable audio stream check if we're already in the desired state before executing the function Signed-off-by: Eryk Brol <eryk.brol@amd.com> Reviewed-by: Jun Lei <Jun.Lei@amd.com> Acked-by: Leo Li <sunpeng.li@amd.com> Signed-off-by: Alex Deucher <alexander.deucher@amd.com>
