SMBusAlert is optional. So, we can say it is not covered by the > "smbus" binding and needs a seperate one. Makes sense? 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'.
