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



Note that most hardware supports being master _and_ slave on the same bus. So,

if you extend a bus driver, please make sure that the driver supports that as

well. In almost all cases, slave support does not need to disable the master

functionality.



Check the i2c-rcar driver as an example.
