+
+Required properties:
+- compatible: should be "socionext,uniphier-uart".
+- reg: offset and length of the register set for the device.
+- interrupts: a single interrupt specifier.
+- clocks: phandle to the input clock.
+
+Optional properties:
+- fifo-size: the RX/TX FIFO size. Defaults to 64 if not specified.
+
+Example:
+ aliases {
+ serial0 = &serial0;
+ };
+
+ serial0: serial@54006800 {
+ compatible = "socionext,uniphier-uart";
+ reg = <0x54006800 0x40>;
+ interrupts = <0 33 4>;
+ clocks = <&uart_clk>;
+ fifo-size = <64>;
+ };
