I guess we need to do something similar to what I did for the palette handling: https://github.com/at91linux/linux-at91/commit/7a256fc44c1892ad3166363ba309d9996a49e7b8 E.G. keep the RBG555/BGR555 format for the old devices, and my proposed change for the new ones. I'll cook something up. -- Bye, Peter Korsgaard -- To unsubscribe from this list: send the line "unsubscribe linux-fbdev" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
