I can confirm that for the Rockchip RK3568 this current series DOES NOT WORK properly yet. The image on the screen is shifted about 100 pixels to the right and does not appear to be a timing issue. This behavior was observed on both the Anbernic RG503 and RG353 portable gaming devices with different screens. These changes were also tested on an RK3326 based device (an Odroid Go Advance) with no noticeable regressions. An example of the issue on multiple devices: https://media.discordapp.net/attachments/973914035890290718/1007407064647221299/IMG_1999.jpg https://media.discordapp.net/attachments/995430498677571604/1003754966932008960/AB25898E-73EC-40A9-BD47-3FB970DDFB31.jpg Given the fact that the DSI controller is identical on the PX30 and RK3568 aside from different grf registers I am assuming the PHY is likely where the bugs are currently. I'm posting this as an RFC in the hopes that someone more knowledgeable than I can help identify the problem.
