How do you know if > all your patches that are timing related are right then? I don't understand your point, or may be I confused with many links that I attached in previous mail. 1. Patch for same panel timings are already in Mainline that was tested on one of the board. [1] 2. Driver from AW, released bsp from BPI-M64-bsp [3] Do you think the above two points are not valid sources?
