[PATCH 01/17] drm/amd/display: Update FAMS2 config cmd

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Alvin Lee <Alvin.Lee2@xxxxxxx>

The FAMS2 stream and sub-state have been separated into
2 different commands. Update the cmd function to send
one command each for the stream and sub-state.
