I'm really confused by this. As far as I understand it it seems
to be doing pinmuxing on the chip using the GPIO bindings which
is itself a bit odd and I don't see anything here that configures
whatever sets the state of the pins. Don't we need another GPIO
to set the vsel-sense inputs on the PMIC?
