Is there anyone you > know who can try this? ... but it should be possible to test on Migo-R even though the vsync pin is missing. Usually people who submit patches do the testing to make sure other platforms won't break. I realize that it may be difficult for you if you don't have any platform to test on. I may be able to find a Migo-R board somewhere, and I'd be happy to add this to my TODO list. Beware that my list is pretty long, so if you're in a rush then I suggest you to test yourself or find someone else to do it for you.
