Device tree configuration for the I2C controller on the XLP9xx/5xx SoC
|
|
|
|
Required properties:
|
|
- compatible : should be "netlogic,xlp980-i2c"
|
|
- reg : bus address start and address range size of device
|
|
- interrupts : interrupt number
|
|
|
|
Optional properties:
|
|
- clock-frequency : frequency of bus clock in Hz
|
|
Defaults to 100 KHz when the property is not specified
|
|
|
|
Example:
|
|
|
|
i2c0: i2c@113100 {
|
|
compatible = "netlogic,xlp980-i2c";
|
|
#address-cells = <1>;
|
|
#size-cells = <0>;
|
|
reg = <0 0x113100 0x100>;
|
|
clock-frequency = <400000>;
|
|
interrupts = <30>;
|
|
interrupt-parent = <&pic>;
|
|
};
