This term is from the QE spec, I didn't invent anything. ;-) "Each pin in the I/O ports can be configured as a general-purpose I/O signal or as a dedicated peripheral interface signal. ...many dedicated peripheral functions are multiplexed onto the ports." > Also, does this depend on gpio_to_chip() patch? Yeah, the point of exported gpio_to_chip is to let us write this function.
