   14   TI DLPC3433 is a MIPI DSI based display controller bridge
   15   for processing high resolution DMD based projectors.
   16 
   17   It has a flexible configuration of MIPI DSI and DPI signal
   18   input that produces a DMD output in RGB565, RGB666, RGB888
   19   formats.
   20 
   21   It supports upto 720p resolution with 60 and 120 Hz refresh
   22   rates.
