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.
