Well just recently Linus W specifically wanted us to use regulator framework for the MMC1 PBIAS rather than pinctrl. That's because from consumer driver point of view, it changes voltage and there's a delay involved. So I guess no conclusion yet, and it's best to do stand alone drivers to deal with those that use pinctrl for the pinctrl specific parts and export it as a regulator for the consumer devices. That's pretty much along the lines what Roger has done, except the transceiver could use the pinctrl-single,bits for the muxing and pinconf.
