 13description: |
 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.
