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>;
|
};
