| |
Short transfer write support for DCS and Generic transfer types share similar way to process command sequence in DSI block so add generic write 2 param transfer type macro so-that the panels which are requesting similar transfer type may process properly.
Also added error check for unsupporting transfer types this make debugging easy for new transfer types.
