* | pinctrl: at91-pio4: Add pinctrl driver | Wenyou Yang | 2016-08-15 | -0/+182 |
AT91 PIO4 controller is a combined gpio-controller, pin-mux and pin-config module. The peripheral's pins are assigned through per-pin based muxing logic. The pin configuration is performed on specific registers which are shared along with the gpio controller. So regard the pinctrl device as a child of atmel_pio4 device.
