description: |
  TI DLPC3433 is a MIPI DSI based display controller bridge
  for processing high resolution DMD based projectors.

  It has a flexible configuration of MIPI DSI and DPI signal
  input that produces a DMD output in RGB565, RGB666, RGB888
  formats.

  It supports upto 720p resolution with 60 and 120 Hz refresh
  rates.
