[PATCH v2 0/6] Add initial support for ATC260x PMICs

From: Cristian Ciocaltea

This is re-spin of the patch series submitted some time ago by Mani,
who added initial support (MFD core and regulators) for the Actions
Semi ATC260x PMICs:
https://lore.kernel.org/lkml/20190617155011.15376-1-manivannan.sadhasivam@xxxxxxxxxx/

The ATC260x family of PMICs integrates Audio Codec, Power management,
Clock generation and GPIO controller blocks. There are currently 3
variants: ATC2603A, ATC2603C and ATC2609A.

In addition to the ATC2609A regulator functionality provided that time,
this patchset adds support for the ATC2603C variant, together with some
new functionalities for both chips: power controller and onkey input.
The ATC2603A variant remains unsupported for the moment.

This has been tested on RoseapplePi, a SBC based on the Action Semi S500
SoC, which integrates ATC2603C PMIC. An initial support for this board
has been already submitted:

Please note that enabling the ATC260x PMICs on the compatible Actions
Semi Owl SoC based boards depends on the following:

* Actions Semi SIRQ driver (for PMIC DTS setup):
https://lore.kernel.org/lkml/cover.1597852360.git.cristian.ciocaltea@xxxxxxxxx/

* I2C Atomic transfers in Actions Semi Owl driver (for proper operation
of the power controller driver):

Thanks,
Cristi
