From: Julian Parkin <[email protected]> [Why] When planes are added or removed from a stream, the change in pipe usage from dynamic MPC combine can cause a second stream using ODM combine to pick a different pipe to combine with.
In this scenario, a different OPP is connected to the ODM without programming its FMT. [How] Reprogram the FMT in dcn20_program_pipe whenever a pipe is newly enabled, or when its opp changes.
