1I2C for R-Car platforms
2
3Required 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
17Optional 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.
