Required properties :
|
||
|
|
- compatible : Must be "cavium,octeon-7890-twsi" or a compatible string
|
||
|
|
- reg : Offset and length of the register set for the device
|
||
|
|
- clocks: Must contain the input clock of the I2C instance
|
||
|
|
- #address-cells = <1>;
|
||
|
|
- #size-cells = <0>;
|
||
|
|
|
||
|
|
Optional properties :
|
||
|
|
- clock-frequency : Desired I2C bus clock frequency in Hz. If not specified,
|
||
|
|
the default 100 kHz frequency will be used. As only Normal, Fast and Fast+
|
||
|
|
modes are implemented, possible values are 100000, 400000 and 1000000.

Example :
|
||
|
|
|
||
|
|
i2c0: i2c@1180000001000 {
|
||
|
|
#address-cells = <1>;
|
||
|
|
#size-cells = <0>;
|
||
|
|
compatible = "cavium,octeon-7890-twsi";
|
||
|
|
reg = <0x11800 0x00001000 0x0 0x200>;
