This is for setting up I3C controller device driver instance
|
|
and also to perform bus initialization (e.g. dynamic address
|
|
assignment).
|
|
|
|
Note that this needs to be done before the device driver
|
|
instances of the connected I2C and I3C devices start
|
|
initializing those devices. This is because some devices
|
|
may not be addressable until addresses are assigned by
|
|
the controller.
