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
