Do the sub-devices actually share these resources, or are you doing
this just to make the code simpler?

They are different resources used by different bucks and ldos without
sharing relations.
I just to make the code simpler.

I don't think that's sensible.

You should only share resources with child devices that consume them.

At first, I separated regulators into two drivers, mt6360-pmic.c and
mt6360-ldo.c, according to default-on power or not.
Then, I merged two drivers into mt6360-regulator.c and merged their
resources as well.
Therefore, for every device of BUCK/LDO, I'll find resources according
to their name and request IRQs.

Okay, so all of the resources are consumed by a single driver?

That is fine then.
