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? [unhandled content-type:application/pgp-signature] |  |
