But, I tested ADV7535 DSI to HDMI bridge or RM67191 DSI panel on i.MX93 11x11 EVK with this series, which works. > Also could you provide your DT configuration? For media blk-ctrl, dsi and lcdif, see: https://pastebin.mozilla.org/aP8tFrPM For adv7535 display pipeline, see: https://pastebin.mozilla.org/89zwvr9Y Note assigned-clock-rates is needed in lcdif DT node to suggest video pll rate.
