i was thinking being an usb cdc device (which i suppose you can also do with the OTG controller) or the debug uart access thing that those newer chromebooks have but that doesnt really have anything to do with the rk3399
I'll see if I can implement it. Woooo my first functional kernel modification
is UOC in e.g. RK3288_UOC0_CON0 "USB OTG Controller"?
got to love those nested abbreviations
