Required properties :



 - reg : Offset and length of the register set for the device

 - compatible : should be "rockchip,rk3066-i2c", "rockchip,rk3188-i2c",

		"rockchip,rk3228-i2c" or "rockchip,rk3288-i2c".

 - compatible: should be one of the following:

   - "rockchip,rk3066-i2c": for rk3066

   - "rockchip,rk3188-i2c": for rk3188

   - "rockchip,rk3228-i2c": for rk3228

   - "rockchip,rk3399-i2c": for rk3399

 - interrupts : interrupt number

 - clocks : parent clock

 - clocks: See ../clock/clock-bindings.txt

   - For older hardware (rk3066, rk3188, rk3228, rk3288):

     - There is one clock that's used both to derive the functional clock

       for the device and as the bus clock.

   - For newer hardware (rk3399): specified by name

     - "i2c": This is used to derive the functional clock.

     - "pclk": This is the bus clock.
