When the pinmux mechanism was added in Kirkwood, the device driver core was not yet providing the possibility of attaching pinmux configurations to all devices, drivers had to do it explicitly, and not all drivers were doing this. Now that the driver core does that in a generic way, it makes sense to attach the pinmux configuration to their corresponding devices. This allows the pinctrl subsystem to show in debugfs to which device is related which pins, for example: pin 41 (PIN41): gpio-leds.1 mvebu-gpio:41 function gpio group mpp41 pin 42 (PIN42): gpio-leds.1 mvebu-gpio:42 function gpio group mpp42 pin 43 (PIN43): gpio-leds.1 mvebu-gpio:43 function gpio group mpp43 Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Acked-by: Andrew Lunn <andrew@lunn.ch> Signed-off-by: Jason Cooper <jason@lakedaemon.net>
