Binding for the Cadence I2C controller Required properties: - reg: Physical base address and size of the controller's register area. - compatible: Should contain one of: * "cdns,i2c-r1p10" Note: Use this when cadence i2c controller version 1.0 is used. * "cdns,i2c-r1p14" Note: Use this when cadence i2c controller version 1.4 is used. - clocks: Input clock specifier. Refer to common clock bindings. - interrupts: Interrupt specifier. Refer to interrupt bindings. - #address-cells: Should be 1. - #size-cells: Should be 0. Optional properties: - clock-frequency: Desired operating frequency, in Hz, of the bus. - clock-names: Input clock name, should be 'pclk'. Example: i2c@e0004000 { compatible = "cdns,i2c-r1p10"; clocks = <&clkc 38>; interrupts = ; reg = <0xe0004000 0x1000>; clock-frequency = <400000>; #address-cells = <1>; #size-cells = <0>; };
