+* Ingenic jz4740 UART
+
+Required properties:
+- compatible : "ingenic,jz4740-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,jz4740-uart";
+ reg = <0x10030000 0x100>;
+
+ interrupt-parent = <&intc>;
+ interrupts = <9>;
+
+ clocks = <&ext>, <&cgu JZ4740_CLK_UART0>;
+ clock-names = "baud", "module";
+};
