Indeed, SMBus Spec [1] mentions about SMBALERT#:
An optional signal that a slave device can use to notify the system
master that it has information for the master

Hence it does make sense to separate it from the smbus binding. I will
post a v4 of this serie with the addition of a generic binding 'smbus-alert'.
