[PATCH 00/33] Add driver for HiSilicon SPMI PMIC for Hikey 970

The Hikey 970 board uses a different PMIC than the one found on Hikey 960.

This PMIC uses a SPMI board.

This patch series backport the OOT drivers from the Linaro's official
tree for this board:

https://github.com/96boards-hikey/linux/tree/hikey970-v4.9

Porting them to upstream, cleaning up coding style issues, solving
driver probing order and adding DT documentation.

I opted to not fold all patches into a single one, in order to:

- Preserve the authorship of the original authors;
- Keep a history of changes.

As this could be harder for people to review, I'll be replying to patch 00/32
with all patches folded. This should help reviewers to see the current
code after the entire series is applied.
