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		"renesas,i2c-r8a7792"
11		"renesas,i2c-r8a7793"
12		"renesas,i2c-r8a7794"
13	- reg: physical base address of the controller and length of memory mapped
14	  region.
15	- interrupts: interrupt specifier.
16	
17	Optional properties:
18	- clock-frequency: desired I2C bus clock frequency in Hz. The absence of this
19	  propoerty indicates the default frequency 100 kHz.
20	- clocks: clock specifier.
21	
22	Examples :
23	
24	i2c0: i2c@e6508000 {
25		#address-cells = <1>;
26		#size-cells = <0>;
27		compatible = "renesas,i2c-r8a7791";
28		reg = <0 0xe6508000 0 0x40>;
29		interrupts = <0 287 IRQ_TYPE_LEVEL_HIGH>;
30		clocks = <&mstp9_clks R8A7791_CLK_I2C0>;
31		clock-frequency = <400000>;
32	};
