-I2C for Spreadtrum platforms
-
-Required properties:
-- compatible: Should be "sprd,sc9860-i2c".
-- reg: Specify the physical base address of the controller and length
-  of memory mapped region.
-- interrupts: Should contain I2C interrupt.
-- clock-names: Should contain following entries:
-  "i2c" for I2C clock,
-  "source" for I2C source (parent) clock,
-  "enable" for I2C module enable clock.
-- clocks: Should contain a clock specifier for each entry in clock-names.
-- clock-frequency: Contains desired I2C bus clock frequency in Hz.
-- #address-cells: Should be 1 to describe address cells for I2C device address.
-- #size-cells: Should be 0 means no size cell for I2C device address.
-
-Optional properties:
-- Child nodes conforming to I2C bus binding
-
-Examples:
-i2c0: i2c@...00000 {
-	compatible = "sprd,sc9860-i2c";
-	reg = <0 0x70500000 0 0x1000>;

-	clock-names = "i2c", "source", "enable";
-	clocks = <&clk_i2c3>, <&ext_26m>, <&clk_ap_apb_gates 11>;
-	clock-frequency = <400000>;
