Binding for Cadence UART Controller



Required properties:

- compatible : should be "cdns,uart-r1p8", or "xlnx,xuartps"

- reg: Should contain UART controller registers location and length.

- interrupts: Should contain UART controller interrupts.

- clocks: Must contain phandles to the UART clocks

  See ../clocks/clock-bindings.txt for details.

- clock-names: Tuple to identify input clocks, must contain "uart_clk" and "pclk"

  See ../clocks/clock-bindings.txt for details.





Example:

	uart@e0000000 {

		compatible = "cdns,uart-r1p8";

		clocks = <&clkc 23>, <&clkc 40>;

		clock-names = "uart_clk", "pclk";

		reg = <0xE0000000 0x1000>;

		interrupts = <0 27 4>;

	};
