- reg: Physical base address and size of the controller's register area.
|
||
|
|
- compatible: Compatibility string. Must be 'cdns,i2c-r1p10'.
|
||
|
|
- 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.
|
||

|
compatible = "cdns,i2c-r1p10";
|
||
|
|
clocks = <&clkc 38>;
|
||
|
|
interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>;
