-Conexant Digicolor I2C controller
-
-Required properties:
- - compatible: must be "cnxt,cx92755-i2c"
- - reg: physical address and length of the device registers
- - interrupts: a single interrupt specifier
- - clocks: clock for the device
- - #address-cells: should be <1>
- - #size-cells: should be <0>
-
-Optional properties:
-- clock-frequency: the desired I2C bus clock frequency in Hz; in
-  absence of this property the default value is used (100 kHz).
-
-Example:
-
-       i2c: i2c@f0000120 {
-               compatible = "cnxt,cx92755-i2c";
-               reg = <0xf0000120 0x10>;
-               interrupts = <28>;
-               clocks = <&main_clk>;
-               clock-frequency = <100000>;
-               #address-cells = <1>;
-               #size-cells = <0>;
-       };
