Hi, using the CM3 with IO board, how do I configure eDP DTS and timing?
Hello, we have brought up Sharp LQ133T1JW01 EDP LCD on Radxa CM3 IO.
This is the dts. Hope it helps you.

Thanks, I have attempted to compile a .dtbo overlay with the appropriate settings changes and included it in the uEnv.txt but cant get it to work, I might will email you the .dtbo and panel datasheet to help troubleshoot.

Hi @sebsd . Did you make any progress? I am also trying to setup eDP panel with not much luck so far.
