+UniPhier I2C controller (FIFO-less)
+
+Required properties:
+- compatible: should be "socionext,uniphier-i2c".
+- #address-cells: should be 1.
+- #size-cells: should be 0.
+- reg: offset and length of the register set for the device.
+- interrupts: a single interrupt specifier.
+- clocks: phandle to the input clock.
+
+Optional properties:
+- clock-frequency: desired I2C bus frequency in Hz.  The maximum supported
+  value is 400000.  Defaults to 100000 if not specified.
+
+Examples:
+
+       i2c0: i2c@58400000 {
+               compatible = "socionext,uniphier-i2c";
+               reg = <0x58400000 0x40>;
+               #address-cells = <1>;
+               #size-cells = <0>;
+               interrupts = <0 41 1>;
+               clocks = <&i2c_clk>;
+               clock-frequency = <100000>;
+       };
