I just skimmed the video and I see your point. I'll need to investigate a bit but I'm up for sending some follow up patches to get these drivers functioning. First lets get the UART working :) Cheers, Tyler -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
