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. Add dt-bingings for it.
