* Ingenic JZ4780 I2C Bus controller
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- compatible: should be "ingenic,jz4780-i2c"
|
||
|
|
- reg: Should contain the address & size of the I2C controller registers.
|
||
|
|
- interrupts: Should specify the interrupt provided by parent.
|
||
|
|
- clocks: Should contain a single clock specifier for the JZ4780 I2C clock.
|
||
|
|
- clock-frequency: desired I2C bus clock frequency in Hz.
|
||
|
|
|
||
|
|
Recommended properties:
|
||
|
|
- pinctrl-names: should be "default";
|
||
|
|
- pinctrl-0: phandle to pinctrl function
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- interrupt-parent: Should be the phandle of the interrupt controller that
|
||
|
|
delivers interrupts to the I2C block.
|
||
|
|
|
||
|
|
