| Microsemi Ocelot pin controller Device Tree Bindings |
| ---------------------------------------------------- |
| |
| Required properties: |
| - compatible : Should be "mscc,ocelot-pinctrl" |
| - reg : Address and length of the register set for the device |
| - gpio-controller : Indicates this device is a GPIO controller |
| - #gpio-cells : Must be 2. |
| The first cell is the pin number and the |
| second cell specifies GPIO flags, as defined in |
| <dt-bindings/gpio/gpio.h>. |
| - gpio-ranges : Range of pins managed by the GPIO controller. |
| |
| |
| The ocelot-pinctrl driver uses the generic pin multiplexing and generic pin |
| configuration documented in pinctrl-bindings.txt. |
| |
| The following generic properties are supported: |
| - function |
| - pins |
| |
| Example: |
| gpio: pinctrl@71070034 { |
| compatible = "mscc,ocelot-pinctrl"; |
| reg = <0x71070034 0x28>; |
| gpio-controller; |
| #gpio-cells = <2>; |
| gpio-ranges = <&gpio 0 0 22>; |
| |
| uart_pins: uart-pins { |
| pins = "GPIO_6", "GPIO_7"; |
| function = "uart"; |
| }; |
| |
| uart2_pins: uart2-pins { |
| pins = "GPIO_12", "GPIO_13"; |
| function = "uart2"; |
| }; |
| }; |
