1I2C for Spreadtrum platforms
2
3Required properties:
4- compatible: Should be "sprd,sc9860-i2c".
5- reg: Specify the physical base address of the controller and length
6  of memory mapped region.
7- interrupts: Should contain I2C interrupt.
8- clock-names: Should contain following entries:
9  "i2c" for I2C clock,
10  "source" for I2C source (parent) clock,
11  "enable" for I2C module enable clock.
12- clocks: Should contain a clock specifier for each entry in clock-names.
13- clock-frequency: Contains desired I2C bus clock frequency in Hz.
14- #address-cells: Should be 1 to describe address cells for I2C device address.
15- #size-cells: Should be 0 means no size cell for I2C device address.
