Have you looked at a "mode" by which you implement just enough of the
slave support to decode smbus notifications ?

This looks like it could be useful when using pmbus devices, as some of
them use smbus notifications fairly often.

Today only one driver calls i2c_handle_smbus_host_notify() (the Intel
one of course).

Although I have not thought about the exact thing you are mentioning, I
want to implement a number of other features for the slave. The thing I am
most interested in is adding support for smbus alert from the slave side.
Nevertheless, I wanted to actually get the driver in before I start trying to do
interesting things. As it is, the slave code satisfies our current purposes and
I do not know of anyone else who wants this feature at this time.

Cheers
