[PATCH 0/8] Add Support for Hi6220 PMIC Hi6553 MFD Core and Regulator

[Fei Wang]

The patch sets add support for Hi6220 PMIC Hi655x MFD core and its regulator driver.
Current testing and support board is Hikey  which is one of Linaro 96boards.
It is an arm64 open source board. For more information about this board,
please access https://www.96boards.org.

This is hardware layout for access PMIC Hi655x from AP SoC Hi6220.
Between PMIC Hi655x and Hi6220, the physical signal channel is SSI.We can use memory-mapped I/O to communicate.
