1 MediaTek MT6397/MT6323 Multifunction Device Driver
3 MT6397/MT6323 is a multifunction device with the following sub modules:
12 It is interfaced to host controller using SPI interface by a proprietary hardware
13 called PMIC wrapper or pwrap. MT6397/MT6323 MFD is a child device of pwrap.
14 See the following for pwarp node definitions:
