[PATCH v2 0/8] Add support MT6316/6363/MT6373 PMICs regulators and MFD

[AngeloGioacchino Del Regno]

Changes in v2:
 - Merged MFD and regulator in one series
 - Split mediatek,mt6316-regulator.yaml in three files as
   suggested by krzk
 - Added interrupt-names list in MT6363/MT6373 bindings as
   suggested by krzk
 - Documented regulator modes in MT6363/73 as suggested by krzk
 - Fixed interrupt and interrupt-names maxItems in both 6363/73
   because, well... I miscounted them in v1 :-)
 - Removed keys from mt6363 binding: the compatible was not yet
   added to the keys binding and doing that will take quite a
   while, as I have to find a way to test the code before that
   as unfortunately my HW does not provide any way to test the
   PMIC keys (thought it did, but then turns out it doesn't...)
 - Completed the mt6363 MFD example with ADC as suggested by Rob
 - Avoided applying regulator schemas multiple times as pointed
   out by Rob (in mfd binding)
 - Fixed MT6363/73 issues pointed out by lkp (eh, sorry, that
   happened during a last minute cleanup... ugh!).
 - Brewed some more coffee :-)


This series adds support for three new MediaTek PMICs: MT6316, MT6363
and MT6373 and their variants - used in board designs featuring the
MediaTek MT8196 Chromebook SoC, or the MT6991 Dimensity 9400 Smartphone
SoC.

In particular, MT6316 is a regulator, but the MT6363 and MT6373 PMICs
are multi-function devices, as they have and expose multiple sub-devices;
moreover, some of those also contain an interrupt controller, managing
internal IPs interrupts: for those, a chained interrupt handler is
registered, which parent is the SPMI controller itself.

This series adds support for all of the MT6316 regulator variants and
for MT6363, MT6373 SPMI PMICs and their interrupt controller.
