Nope, only after the mux register changes. I've verified it on am3730 with off-idle for both serial and wl12xx. > I didn't pick up your padconf patches yet -seems i need to be in sync :) Well you need those for proper wake-up event support.. > Below the diff I used to verify IO wake up (It follows old IO daisy > chain hanlding models in hwmod before DT): ..then these changes not needed with the pinctrl-single changes.
