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 Cristian Ciocaltea (6): dt-bindings: input: Add reset-time-sec common property dt-bindings: mfd: Add Actions Semi ATC260x PMIC binding mfd: Add MFD driver for ATC260x PMICs regulator: Add regulator driver for ATC260x PMICs power: reset: Add poweroff driver for ATC260x PMICs input: atc260x: Add onkey driver for ATC260x PMICs Manivannan Sadhasivam (1): MAINTAINERS: Add entry for ATC260x PMIC .../devicetree/bindings/input/input.yaml | 7 + .../bindings/mfd/actions,atc260x.yaml | 183 ++++++ MAINTAINERS | 12 + drivers/input/misc/Kconfig | 11 + drivers/input/misc/Makefile | 2 +- drivers/input/misc/atc260x-onkey.c | 305 ++++++++++ drivers/mfd/Kconfig | 18 + drivers/mfd/Makefile | 3 + drivers/mfd/atc260x-core.c | 293 ++++++++++ drivers/mfd/atc260x-i2c.c | 64 +++ drivers/power/reset/Kconfig | 8 +- drivers/power/reset/Makefile | 1 + drivers/power/reset/atc260x-poweroff.c | 263 +++++++++ drivers/regulator/Kconfig | 8 + drivers/regulator/Makefile | 1 + drivers/regulator/atc260x-regulator.c | 539 ++++++++++++++++++ include/linux/mfd/atc260x/atc2603c.h | 281 +++++++++ include/linux/mfd/atc260x/atc2609a.h | 308 ++++++++++ include/linux/mfd/atc260x/core.h | 58 ++ 19 files changed, 2363 insertions(+), 2 deletions(-) create mode 100644 Documentation/devicetree/bindings/mfd/actions,atc260x.yaml create mode 100644 drivers/input/misc/atc260x-onkey.c create mode 100644 drivers/mfd/atc260x-core.c create mode 100644 drivers/mfd/atc260x-i2c.c create mode 100644 drivers/power/reset/atc260x-poweroff.c create mode 100644 drivers/regulator/atc260x-regulator.c create mode 100644 include/linux/mfd/atc260x/atc2603c.h create mode 100644 include/linux/mfd/atc260x/atc2609a.h create mode 100644 include/linux/mfd/atc260x/core.h
