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

I have just realized I had omitted the changelog - sorry:

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
  * Requires support for I2C Atomic transfers in the Owl driver (already submitted)
- Added onkey driver: exposes the power button as an input device
- Added yaml binding doc
- Rebased patchset on kernel v5.9-rc1

Kind regards,
Cristi
