[PATCH v5 0/5] Add Support for Hi6220 PMIC Hi6553 MFD Core

[Chen Feng]

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 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.

  |    Hi6220      |   SSI bus   |   Hi655x    |
  |                |-------------|             |
  |                |(REGMAP_MMIO)|             |
  +----------------+             +-------------+

  V2: Code refactoring of regulator.

  V3: Drop mtcmos from this patch and use regmap-irq.

  V4: Move the vset-table to driver code and donot open code for it.

  V5: Use of_match to get dt-data
