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 On Sat, Aug 22, 2020 at 01:19:46AM +0300, Cristian Ciocaltea wrote: > 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.
