I could use PIN_CONFIG_POWER_SOURCE for controlling the PBIAS for omap MMC. But there's also a status bit that needs to be checked for that. I think there was some other similar mux register for USB PHY that has a status register. So I'm wondering should the checking for status bit be handled in the pinctrl consume driver? Or should we have some bindings for that?
