* 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).

- uart-use-irda: Indicate the UART use IRDA mode.



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;

	};
