1Microsemi Ocelot pin controller Device Tree Bindings 2---------------------------------------------------- 3 4Required properties: 5 - compatible : Should be "mscc,ocelot-pinctrl", 6 "mscc,jaguar2-pinctrl", "microchip,sparx5-pinctrl", 7 "mscc,luton-pinctrl" or "mscc,serval-pinctrl" 8 - reg : Address and length of the register set for the device 9 - gpio-controller : Indicates this device is a GPIO controller 10 - #gpio-cells : Must be 2. 11 The first cell is the pin number and the 12 second cell specifies GPIO flags, as defined in 13 <dt-bindings/gpio/gpio.h>. 14 - gpio-ranges : Range of pins managed by the GPIO controller. 15 16 17The ocelot-pinctrl driver uses the generic pin multiplexing and generic pin 18configuration documented in pinctrl-bindings.txt. 19 20The following generic properties are supported: 21 - function 22 - pins 23 24Example: 25 gpio: pinctrl@71070034 { 26 compatible = "mscc,ocelot-pinctrl"; 27 reg = <0x71070034 0x28>; 28 gpio-controller; 29 #gpio-cells = <2>; 30 gpio-ranges = <&gpio 0 0 22>; 31 32 uart_pins: uart-pins { 33 pins = "GPIO_6", "GPIO_7"; 34 function = "uart"; 35 }; 36 37 uart2_pins: uart2-pins { 38 pins = "GPIO_12", "GPIO_13"; 39 function = "uart2"; 40 }; 41 }; 42
