* implement calls to register/unregister the slave and add those to the
struct i2c_algorithm. When registering, you probably need to set the i2c
slave address and enable slave specific interrupts. If you use runtime pm, you
- should use pm_runtime_forbid() because your device usually needs to be powered
- on always to be able to detect its slave address. When unregistering, do the
- inverse of the above.

* Catch the slave interrupts and send appropriate i2c_slave_events to the backend.
