0001 I2C for Spreadtrum platforms
0002
0003 Required properties:
0004 - compatible: Should be "sprd,sc9860-i2c".
0005 - reg: Specify the physical base address of the controller and length
0006 of memory mapped region.
0007 - interrupts: Should contain I2C interrupt.
0008 - clock-names: Should contain following entries:
0009 "i2c" for I2C clock,
0010 "source" for I2C source (parent) clock,
0011 "enable" for I2C module enable clock.
0012 - clocks: Should contain a clock specifier for each entry in clock-names.
0013 - clock-frequency: Constains desired I2C bus clock frequency in Hz.
0014 - #address-cells: Should be 1 to describe address cells for I2C device address.
0015 - #size-cells: Should be 0 means no size cell for I2C device address.

0017 Optional properties:
0018 - Child nodes conforming to I2C bus binding
