+RDA Micro UART
+
+Required properties:
+- compatible : "rda,8810pl-uart" for RDA8810PL SoCs.
+- reg : Offset and length of the register set for the device.
+- interrupts : Should contain UART interrupt.
+- clocks : Phandle to the input clock.
+
+
+Example:
+
+ uart2: serial@20a90000 {
+ compatible = "rda,8810pl-uart";
+ reg = <0x20a90000 0x1000>;
+ interrupts = <11 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&uart_clk>;
+ };
