+I2C for R-Car platforms
+
+Required properties:
+- compatible: Must be one of
+ "renesas,i2c-rcar"
+ "renesas,i2c-r8a7778"
+ "renesas,i2c-r8a7779"
+ "renesas,i2c-r8a7790"
+ "renesas,i2c-r8a7791"
+ "renesas,i2c-r8a7792"
+ "renesas,i2c-r8a7793"
+ "renesas,i2c-r8a7794"
+- reg: physical base address of the controller and length of memory mapped
+ region.
+- interrupts: interrupt specifier.
+
+Optional properties:
+- clock-frequency: desired I2C bus clock frequency in Hz. The absence of this
+ propoerty indicates the default frequency 100 kHz.
+- clocks: clock specifier.
+
+Examples :
+
+i2c0: i2c@e6508000 {
+ #address-cells = <1>;
+ #size-cells = <0>;
+ compatible = "renesas,i2c-r8a7791";
+ reg = <0 0xe6508000 0 0x40>;
+ interrupts = <0 287 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&mstp9_clks R8A7791_CLK_I2C0>;
+ clock-frequency = <400000>;
+};
