From: Rodrigo Siqueira <Rodrigo.Siqueira@xxxxxxx> Since DC version 3.2.226, DC started to use a new internal commit sequence that better deals with hardware limitations. Usually, DC adopts split pipe dynamics to improve the display bandwidth and, in some cases, to save power. This commit sets MPC_SPLIT_DYNAMIC for DCN301, improving the bandwidth and fixing the cursor bug on KDE when it tries hardware rotation.
