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.
