The CCI provides I2C masters for one (msm8916) or two i2c busses (msm8996, |
|
sdm845 and sm8250), described as subdevices named "i2c-bus@0" and "i2c-bus@1". |

|
Definition: Index of the CCI bus/master |
|
|
|
- clock-frequency: |
|
Usage: optional |
|
Value type: <u32> |
|
Definition: Desired I2C bus clock frequency in Hz, defaults to 100 |
|
kHz if omitted. |
