+Socionext Milbeaut UART controller
+
+Required properties:
+- index: must be 0
+- compatible: should be "socionext,milbeaut-m10v-usio-uart".
+- reg: offset and length of the register set for the device.
+- interrupts: two interrupts specifier.
+- clocks: phandle to the input clock.
+- interrupt-names: should be "rx", "tx".
+
+Optional properties:
+- uart-flow-enable: flow control enable.
+
+Example:
+ usio1: usio_uart@1e700010 {
+ index = <0>;
+ compatible = "socionext,milbeaut-m10v-usio-uart";
+ reg = <0x1e700010 0x10>;
+ interrupts = <0 141 0x4>, <0 149 0x4>;
+ interrupt-names = "rx", "tx";
+ clocks = <&hclk>;
+ uart-flow-enable;
+ };
