Subject: [PATCH v11 3/5] mfd: Add support for the MediaTek MT6358 PMIC
This adds support for the MediaTek MT6358 PMIC. This is a
multifunction device with the following sub modules:
- Regulator
- RTC
- Codec
- Interrupt
It is interfaced to the host controller using SPI interface
by a proprietary hardware called PMIC wrapper or pwrap.
MT6358 MFD is a child device of the pwrap.
