This feature is another pet-peeve of mine. It's a hack that people
started using and now it's in all kinds of drivers. It doesn't really
explain what it actually does, and it implements it badly.

Let's deprecate it officially, add it to MAINTAINERS keywords so that it
pops up on our radars when used again, add a task to track it and I plan
to use the power sequencing subsystem to handle the cases where
non-exclusive access to GPIOs is required.

Some like drivers/fsi/fsi-master-aspeed.c seem to be just a bug,
are all non-regulator users bugs?

In general though:
