MediaTek Helio X10 MT6795 - MT6331/6332 Regulators
Merge series from AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>: In an effort to give some love to the apparently forgotten MT6795 SoC, I am upstreaming more components that are necessary to support platforms powered by this one apart from a simple boot to serial console. This series adds support for the regulators found in MT6331 and MT6332 main/companion PMICs. Adding support to each driver in each subsystem is done in different patch series as to avoid spamming uninteresting patches to maintainers. Tested on a MT6795 Sony Xperia M5 (codename "Holly") smartphone.
