[PATCH v4 5/9] mfd: Add support for the MediaTek MT6359 PMIC
This adds support for the MediaTek MT6359 PMIC. This is a multifunction device with the following sub modules: - Codec - Interrupt - Regulator - RTC It is interfaced to the host controller using SPI interface by a proprietary hardware called PMIC wrapper or pwrap. MT6359 MFD is a child device of the pwrap.
