Yes, I'm aware of this. Technically the isp1704 does not provide the
5 volt line, but for the system as a whole that fact does not really
matter.

The isp1704 can provide its functionality via the regulator API
as a simple regulator device. It provides information about the
power "it can supply".

The bq24150a on the other hand can just use the regulator via the
consumer interface.

The regulator framework provides capabilities for events:
"Regulators can notify consumers of external events"
