description: |
|
|
Apple SoCs such as the M1 come with a I2C controller based on the one found
|
|
in machines with P. A. Semi's PWRficient processors.
|
|
The bus is used to communicate with e.g. USB PD chips or the speaker
|
|
amp.

|
Desired I2C bus clock frequency in Hz. If not specified, 100 kHz will be
|
|
used. This frequency is generated by dividing the reference clock.
|
|
Allowed values are between ref_clk/(16*4) and ref_clk/(16*255).
