[PATCH 00/14] ARM: berlin: bisect compatible simple-mfd conversion

[Sebastian Hesselbarth]

This is a patch set reworking Antoine's patches to move Berlin's system and
chip controller nodes to simple-mfd registered sub-nodes in a bisect compatible
way.

Compared to Antoine's patches, I basically first converted the drivers to
deal with both single node and simple-mfd sub-node registration, then move the
DT nodes over to simple-mfd, and finally drop the old way of registration.

I decided to squash the BG2/BG2CD/BG2Q DT changes into a single patch where
applicable instead of the clock node rework patches. I also left the Acked-by
from Phillip Zabel (reset), Linus Walleij (pinctrl), and Stephen Boyd (clk)
in place for the driver changes as the outcome is the same at the end.

I am still planing to get this into v4.2 as soon as possible, so if Arnd is
now happy with the dependency of the patches and none of the maintainers is
against it, I'll prepare a PR next week.

@Arnd: This is still based on v4.1-rc1 as I cannot see a stable branch for
simple-mfd support. Anything specific you want me to remind you that this
depends on simple-mfd?
