+UniPhier I2C controller (FIFO-builtin)
+
+Required properties:
+- compatible: should be "socionext,uniphier-fi2c".
+- #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@58780000 {
+ compatible = "socionext,uniphier-fi2c";
+ reg = <0x58780000 0x80>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+ interrupts = <0 41 4>;
+ clocks = <&i2c_clk>;
+ clock-frequency = <100000>;
+ };
