Subject: [PATCH v8 0/5] Add Support for Hi6220 PMIC Hi6553 MFD Core

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.

+----------------+             +-------------+

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 regulators_node and of_match, donot open code fot it.

V7: Change the constraints into hikey.dts and fix code in PMIC.

V8: Change format in document, and fix bit mask in regulator.

Chen Feng (5):
  mfd: hi655x: Add document for mfd hi665x PMIC
  regulator: hi655x: Document for hi655x regulator
  mfd: hi655x: Add MFD driver for hi655x
  regulator: hi655x: enable regulator for hi655x PMIC
  arm64: dts: hisilicon: Add hi655x pmic dts node
