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>; };
