+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>;
+	};
