1	I2C for R-Car platforms
2	
3	Required properties:
4	- compatible: Must be one of
5		"renesas,i2c-rcar"
6		"renesas,i2c-r8a7778"
7		"renesas,i2c-r8a7779"
8		"renesas,i2c-r8a7790"
9		"renesas,i2c-r8a7791"
10	- reg: physical base address of the controller and length of memory mapped
11	  region.
12	- interrupts: interrupt specifier.
13	
14	Optional properties:
15	- clock-frequency: desired I2C bus clock frequency in Hz. The absence of this
16	  propoerty indicates the default frequency 100 kHz.
17	- clocks: clock specifier.
18	
19	Examples :
20	
21	i2c0: i2c@e6508000 {
22		#address-cells = <1>;
23		#size-cells = <0>;
24		compatible = "renesas,i2c-r8a7791";
25		reg = <0 0xe6508000 0 0x40>;
26		interrupts = <0 287 IRQ_TYPE_LEVEL_HIGH>;
27		clocks = <&mstp9_clks R8A7791_CLK_I2C0>;
28		clock-frequency = <400000>;
29	};
