|
|
|
|
Required properties :
|
|
|
|
- compatible : should be "wm,wm8505-i2c"
|
|
- reg : Offset and length of the register set for the device
|
|
- interrupts : <IRQ> where IRQ is the interrupt number
|
|
- clocks : phandle to the I2C clock source
|
|
|
|
Optional properties :
|
|
|
|
- clock-frequency : desired I2C bus clock frequency in Hz.
|
|
Valid values are 100000 and 400000.
|
|
Default to 100000 if not specified, or invalid value.
|
|
|
|
Example :
|
|
|
|
i2c_0: i2c@d8280000 {
|
|
compatible = "wm,wm8505-i2c";
|
|
reg = <0xd8280000 0x1000>;
|
|
interrupts = <19>;
|
|
clocks = <&clki2c0>;
|
|
clock-frequency = <400000>;
|
|
};
