1 Microsemi Ocelot pin controller Device Tree Bindings
2 ----------------------------------------------------
5 - compatible : Should be "mscc,ocelot-pinctrl"
6 - reg : Address and length of the register set for the device
7 - gpio-controller : Indicates this device is a GPIO controller
8 - #gpio-cells : Must be 2.
9 The first cell is the pin number and the
10 second cell specifies GPIO flags, as defined in
11 <dt-bindings/gpio/gpio.h>.
12 - gpio-ranges : Range of pins managed by the GPIO controller.
15 The ocelot-pinctrl driver uses the generic pin multiplexing and generic pin
16 configuration documented in pinctrl-bindings.txt.
18 The following generic properties are supported:
23 gpio: pinctrl@71070034 {
24 compatible = "mscc,ocelot-pinctrl";
25 reg = <0x71070034 0x28>;
28 gpio-ranges = <&gpio 0 0 22>;
30 uart_pins: uart-pins {
31 pins = "GPIO_6", "GPIO_7";
35 uart2_pins: uart2-pins {
36 pins = "GPIO_12", "GPIO_13";
