+* Ingenic jz4780 UART
+
+Required properties:
+- compatible : "ingenic,jz4780-uart"
+- reg : offset and length of the register set for the device.
+- interrupts : should contain uart interrupt.
+- clocks : phandles to the module & baud clocks.
+- clock-names: tuple listing input clock names.
+	Required elements: "baud", "module"
+
+Example:
+
+uart0: serial@10030000 {
+	compatible = "ingenic,jz4780-uart";
+	reg = <0x10030000 0x100>;
+
+	interrupt-parent = <&intc>;
+	interrupts = <51>;
+
+	clocks = <&ext>, <&cgu JZ4780_CLK_UART0>;
+	clock-names = "baud", "module";
+};
