3eaeb47563 regulator: core: optimize devm_regulator_bulk_get()
When performing this bulk operation, there is no need to track every supply
individually. It is more efficient to treat entire group as a single
managed resource.

a8bd42a977 regulator: core: have _regulator_get() accept get_type argument
Instead of separate "exclusive" and "allow_dummy" arguments, that formed 3
valid combinations (normal, exclusive and optional) and an invalid one,
let's accept explicit "get_type", like we did in devm-managed code.

565f9b073f regulator: Remove support for optional supplies in the bulk API
The patch was based on my missinterpretation of the API and only
accidentally worked for me. Let's clean it out to not confuse others.

This reverts commit 3ff3f518a1.

3ff3f518a1 regulator: Make bulk API support optional supplies
Make it possible to use the bulk API with optional supplies, by allowing
the consumer to marking supplies as optional in the regulator_bulk_data.

046db763aa regulator: core: Add devres versions of notifier registration
Add devm_regulator_register_notifier, this adds the resource against the
device for the consumer supply we are registering the notifier for. There
seem to be few use-cases where this wouldn't be the users intention and
this ensures the notifiers will always be removed at the correct time.

a06ccd9c37 regulator: core: Add ability to create a lookup alias for supply
These patches add the ability to create an alternative device on which
a lookup for a certain supply should be conducted.

A common use-case for this would be devices that are logically
represented as a collection of drivers within Linux but are are
presented as a single device from device tree. It this case it is
necessary for each sub device to locate their supply data on the main
device.

0cdfcc0f93 regulator: core: Split devres code out into a separate file
Cut down on the size of core.c a bit more and ensure that the devres
versions of things don't do too much peering inside the internals of
the APIs they wrap.
