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";
};
};
