ed to be flagged as requiring synchronisation with a tearing effect control signal - either the inband method or a dedicated line. I suspect many hardware implementations will have a specific method for transferring pixel data in a DSI command mode transfer. The command sending period during video mode should probably be configurable on a per-transfer basis. Some commands have to be synchronised with vertical blanking, others do not. This could perhaps be combined with a wider configuration option for a given panel or interface. Similarly, selection of low power (LP) and high speed (HS) mode on a per-transfer basis can be needed for some panels. Is there a mechanism for controlling ultra-low power state (ULPS) entry? Also, is there a method for sending arbitrary trigger messages (eg the reset trigger)? Thanks, Bert. -- Bert Kenward Software Engineer Broadcom Mobile Platform Solutions Cambridge, UK
