* Microchip Universal Asynchronous Receiver Transmitter (UART)

Required properties:
- compatible: Should be "microchip,pic32mzda-uart"
- reg: Should contain registers location and length
- interrupts: Should contain interrupt
- clocks: Phandle to the clock.
          See: Documentation/devicetree/bindings/clock/clock-bindings.txt
- pinctrl-names: A pinctrl state names "default" must be defined.
- pinctrl-0: Phandle referencing pin configuration of the UART peripheral.
             See: Documentation/devicetree/bindings/pinctrl/pinctrl-binding.txt

Optional properties:
- cts-gpios: CTS pin for UART

Example:
	uart1: serial@1f822000 {
		compatible = "microchip,pic32mzda-uart";
		reg = <0x1f822000 0x50>;
		interrupts = <112 IRQ_TYPE_LEVEL_HIGH>,
			<113 IRQ_TYPE_LEVEL_HIGH>,
			<114 IRQ_TYPE_LEVEL_HIGH>;
		clocks = <&rootclk PB2CLK>;
		pinctrl-names = "default";
		pinctrl-0 = <&pinctrl_uart1
				&pinctrl_uart1_cts
				&pinctrl_uart1_rts>;
		cts-gpios = <&gpio1 15 0>;
	};
