8.4.4.6 Video Format Parameters

It is the responsibility of the GPU software to program the DSIx6 Video Registers with the Video format that is expected to be displayed on the eDP panel. The DSIx6 expects the parameters in Table 8-7 to be programmed. The DSIx6 will use these parameters to determine the DisplayPort MSA parameters that are transmitted over DisplayPort every vertical blanking period. These MSA parameters are used by the eDP panel to recreate the video format provided on the DSI interface.
