1I2C for Hisilicon hix5hd2 chipset platform
2
3Required properties:
4- compatible: Must be "hisilicon,hix5hd2-i2c"
5- reg: physical base address of the controller and length of memory mapped
6     region.
7- interrupts: interrupt number to the cpu.
8- #address-cells = <1>;
9- #size-cells = <0>;
10- clocks: phandles to input clocks.

12Optional properties:
13- clock-frequency: Desired I2C bus frequency in Hz, otherwise defaults to 100000
14- Child nodes conforming to i2c bus binding
