1 | Binding for the Cadence I2C controller |
2 | ||
3 | Required properties: | |
4 | - reg: Physical base address and size of the controller's register area. | |
63cab195 AKV |
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 | ||
15 | Optional properties: | |
16 | - clock-frequency: Desired operating frequency, in Hz, of the bus. | |
17 | - clock-names: Input clock name, should be 'pclk'. | |

19 | Example: | |
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>; | |
