+Xilinx Axi Uartlite controller Device Tree Bindings
+---------------------------------------------------------
+
+Required properties:
+- compatible : Can be either of
+ "xlnx,xps-uartlite-1.00.a"
+ "xlnx,opb-uartlite-1.00.b"
+- reg : Physical base address and size of the Axi Uartlite
+ registers map.
+- interrupts : Should contain UART controller interrupts.
+
+Optional properties:
+- port-number : Set Uart port number
+- clock-names : Should be "s_axi_aclk"
+- clocks : Input clock specifier. Refer to common clock bindings.
+
+Example:
+serial@800c0000 {
+ compatible = "xlnx,xps-uartlite-1.00.a";
+ reg = <0x0 0x800c0000 0x10000>;
+ interrupts = <0x0 0x6e 0x1>;
+ port-number = <0>;
+};
