1Binding for the Cadence I2C controller 2 3Required properties: 4 - reg: Physical base address and size of the controller's register area. 5 - compatible: Compatibility string. Must be 'cdns,i2c-r1p10'. 6 - clocks: Input clock specifier. Refer to common clock bindings. 7 - interrupts: Interrupt specifier. Refer to interrupt bindings. 8 - #address-cells: Should be 1. 9 - #size-cells: Should be 0. 10 11Optional properties: 12 - clock-frequency: Desired operating frequency, in Hz, of the bus. 13 - clock-names: Input clock name, should be 'pclk'. 14 15Example: 16 i2c@e0004000 { 17 compatible = "cdns,i2c-r1p10"; 18 clocks = <&clkc 38>; 19 interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>; 20 reg = <0xe0004000 0x1000>; 21 clock-frequency = <400000>; 22 #address-cells = <1>; 23 #size-cells = <0>; 24 }; 25
