This way a user can provide a gpio-ranges property defined for a pinmux, easing muxing of gpio functions. Provided that the pin controller implementents the pinmux op .gpio_request_enable(), pins will automatically be muxed to their GPIO function when requested. Signed-off-by: Sander Vanheule --- Álvaro has submitted a similar patch today. My implementation's impact is more limited, but I hadn't gotten around to submitting it yet.
