| 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 = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>; |
| reg = <0xe0004000 0x1000>; |
| clock-frequency = <400000>; |
| #address-cells = <1>; |
| #size-cells = <0>; |
| }; |
