Subject: [PATCH v4 0/7] Add initial support for ATC260x PMICs
Date:   Tue, 29 Dec 2020 19:31:15 +0200

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.

This is re-spin of the v1 patch series submitted some time ago by
Mani, who provided the MFD and regulator drivers for ATC2609A:
https://lore.kernel.org/lkml/20190617155011.15376-1-manivannan.sadhasivam@linaro.org/

Since v2, I added support for ATC2603C, together with some new
functionalities for both chips: power controller and onkey input.
The ATC2603A chip type remains unsupported for the moment.

This has been tested on RoseapplePi, a SBC based on the Actions Semi S500
SoC, which integrates the ATC2603C variant of the PMIC.

Note that enabling the ATC260x PMICs on compatible Actions Semi Owl SoC
based boards depends on:

* the Actions Semi SIRQ driver (for PMIC DTS setup), merged in v5.10:
  https://lore.kernel.org/lkml/cover.1600114378.git.cristian.ciocaltea@gmail.com/

* the atomic transfers in Owl I2C driver (for power controller), merged in v5.11:
  https://lore.kernel.org/lkml/cover.1602190168.git.cristian.ciocaltea@gmail.com/

Additionally, please note that I have taken the authorship for the MFD
and regulator drivers patches, considering the original code has been
modified to a large extent.

Thanks,
Cristi

Changes in v4:
- Updated MFD driver according to Lee's review
- Handled ATC2603C's LDO12 fixed regulator per Mark's suggestion
- Rebased patchset on v5.11-rc1

Changes in v3:
- Integrated feedback from Mani, Rob, Mark, Sebastian, Dmitry
- Fixed issues reported by Lee's kernel test robot
- Added new patch for 'reset-time-sec' DT binding property
- Rebased patchset on v5.10-rc6

Changes in v2:
- Reworked MFD core & I2C driver
  * Integrated Lee's feedback
  * Added support for using the regmap within atomic contexts
  * Added support for ATC2603C chip variant
  * Reorganized KConfig entries
- Improved regulator driver
  * Added support for ATC2603C variant
  * Used helper macros for more compact specification of regulator_desc items
  * Added more regulator capabilities
- Added power controller driver
  * Provides system poweroff/reboot functionalities
  * Depends on atomic transfers in the Owl I2C driver
- Added onkey driver: exposes the power button as an input device
- Added yaml binding doc
- Rebased patchset on kernel v5.9-rc1
