I don't see why we should not allow changing the mux state with pinconf too, after all it's the mux/pin that's locked, not the functionality of the pin. An example of this would be remuxing a shared UART line between rx and tx. Those kind of cases could be defined as PMX_DIRECTION_INPUT and PMX_DIRECTION_OUTPUT so driver could call Linux generic functions for those if implemented.
