[PATCH v4 0/4] MediaTek Helio X10 MT6795 - MT6331/6332 Regulators

From: AngeloGioacchino Del Regno

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.

Changes in v4:
- Rebased on next-20220912

Changes in v3:
- Sorry, one of the commits picked both the pre-rename file and
the new one... the v3 fixes the mt6332 bindings commit.
- Changed comment style on top for mt633[12]-regulator.c as
suggested (missed that in v2)

Changes in v2:
- Refactored description in dt-bindings
- Simplified get_status() function and removed callback
where not needed
- Simplified set_mode()/get_mode() functions and removed
callback where not needed
- Added new regulator_ops for no_qi (no .get_status) and
for no_ms (no .{get, set}_mode)
- Fixed vsel mask on some regulators and removed pattern of
repeated voltage entries present in some voltage tables,
avoiding to set higher bits for safety
- Reordered regulators (and some formatting fixes) in
mt6331-regulator.c in per-type alphabetic order
