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.
