1Binding for the Cadence I2C controller 2 3Required properties: 4 - reg: Physical base address and size of the controller's register area. 5 - compatible: Should contain one of: 6 * "cdns,i2c-r1p10" 7 Note: Use this when cadence i2c controller version 1.0 is used. 8 * "cdns,i2c-r1p14" 9 Note: Use this when cadence i2c controller version 1.4 is used. 10 - clocks: Input clock specifier. Refer to common clock bindings. 11 - interrupts: Interrupt specifier. Refer to interrupt bindings. 12 - #address-cells: Should be 1. 13 - #size-cells: Should be 0. 14 15Optional properties: 16 - clock-frequency: Desired operating frequency, in Hz, of the bus. 17 - clock-names: Input clock name, should be 'pclk'. 18 19Example: 20 i2c@e0004000 { 21 compatible = "cdns,i2c-r1p10"; 22 clocks = <&clkc 38>; 23 interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>; 24 reg = <0xe0004000 0x1000>; 25 clock-frequency = <400000>; 26 #address-cells = <1>; 27 #size-cells = <0>; 28 }; 29
