I've been involved in the earlier revisions already, so this version already implements the review-comments I had. I've also gave this a spin on 4.3-rc6 with usb-next merged in on a rk3288-firefly, so Reviewed-by: Heiko Stuebner Tested-by: Heiko Stuebner If the first two patches get picked up, I'll pick the two dts patches afterwards. Thanks Heiko
