| 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. |
