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. Regards, Tony
