regulator: Add support for MediaTek MT6316 SPMI PMIC Regulators
Add a driver for the regulators found on all types of the MediaTek
MT6316 SPMI PMIC, fully controlled by SPMI interface and featuring
four step down DCDC (buck) converters.
In particular, this includes support for:
- MT6316(BP/VP): 2+2 Phase (Phase 1: buck1+2, Phase 2: buck3+4)
- MT6316(CP/HP/KP): 3+1 Phase (Phase 1: buck1+2+4, Phase 2: buck3)
- MT6316(DP/TP): 4+0 Phase (Single phase, buck1+2+3+4)
Please note that the set/clear registers for the enable bits are
not documented in the datasheet version that I used as reference,
but those are used in the downstream driver and I verified that
are actually working as expected.
Besides, it's also worth clearly mentioning that the MT6316 PMICs
voltage selector register uses a weird 9-bits Big Endian format,
for which a driver-private helper is provided.
