  13 description: |
  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.
