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?
