* Cirrus Logic CLPS711X Universal Asynchronous Receiver/Transmitter (UART)

Required properties:
- compatible: Should be "cirrus,clps711x-uart".
- reg: Address and length of the register set for the device.
- interrupts: Should contain UART TX and RX interrupt.
- clocks: Should contain UART core clock number.
- syscon: Phandle to SYSCON node, which contain UART control bits.

Optional properties:
- uart-use-ms: Indicate the UART has modem signal (DCD, DSR, CTS).

Note: Each UART port should have an alias correctly numbered
in "aliases" node.

Example:
	aliases {
		serial0 = &uart1;
	};

	uart1: uart@80000480 {
		compatible = "cirrus,clps711x-uart";
		reg = <0x80000480 0x80>;
		interrupts = <12 13>;
		clocks = <&clks 11>;
		syscon = <&syscon1>;
		uart-use-ms;
	};
