-Microsemi Ocelot pin controller Device Tree Bindings
-----------------------------------------------------
-
-Required properties:
- - compatible		: Should be "mscc,ocelot-pinctrl",
-			  "mscc,jaguar2-pinctrl", "microchip,sparx5-pinctrl",
-			  "mscc,luton-pinctrl" or "mscc,serval-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";
-		};
-	};
