No, I don't think it works. Or at least I can't figure out how. pinctrl-single doesn't allow to freely set the bits, but requires the pins to have similar bit structure (function-mask). In CONTROL_DSIPHY, DSI1 and DSI2 have different bit structures. I don't understand why pinctrl-single tries so hard to fit things into one mold... tomi
