I like that we have it done in i2c core instead of having drivers
implementing it individually. Since you are saying that handling host
notify is property of the slave/driver maybe we should be adding a flag
to the *i2c_driver* structure to let i2c core that we want to have host
notify mapped as interrupt if "native" interrupt is not supplied by the
platform code?

Thanks.
