See the cover letter from v1: https://patchwork.kernel.org/project/linux-soc/cover/20230823161012.6986-1-kabel@kernel.org/ I am also sending this to specific subsystem maintainers as requested by Krzysztof. Changes since v1: - incorporated small changes requested by Krzysztof Kozlowski - in order to make reviewing simpler, I split the second patch, which implements the MCU driver, into four incremental patches: - patch 2/7 adds basic driver skeleton - patch 3/7 adds GPIO support - patch 4/7 adds board poweroff and wakeup support - patch 5/7 adds MCU watchdog support Marek Marek Behún (7): dt-bindings: arm: add cznic,turris-omnia-mcu binding platform: cznic: Add preliminary support for Turris Omnia MCU platform: cznic: turris-omnia-mcu: Add support for MCU connected GPIOs platform: cznic: turris-omnia-mcu: Add support for poweroff and wakeup platform: cznic: turris-omnia-mcu: Add support for MCU watchdog ARM: dts: turris-omnia: Add MCU system-controller node ARM: dts: turris-omnia: Add GPIO key node for front button .../sysfs-bus-i2c-devices-turris-omnia-mcu | 77 ++ .../bindings/arm/cznic,turris-omnia-mcu.yaml | 67 ++ MAINTAINERS | 4 + .../dts/marvell/armada-385-turris-omnia.dts | 35 +- drivers/platform/Kconfig | 2 + drivers/platform/Makefile | 1 + drivers/platform/cznic/Kconfig | 47 + drivers/platform/cznic/Makefile | 7 + .../platform/cznic/turris-omnia-mcu-base.c | 273 +++++ .../platform/cznic/turris-omnia-mcu-gpio.c | 971 ++++++++++++++++++ .../cznic/turris-omnia-mcu-sys-off-wakeup.c | 245 +++++ .../cznic/turris-omnia-mcu-watchdog.c | 126 +++ drivers/platform/cznic/turris-omnia-mcu.h | 164 +++ include/linux/turris-omnia-mcu-interface.h | 194 ++++ 14 files changed, 2212 insertions(+), 1 deletion(-) create mode 100644 Documentation/ABI/testing/sysfs-bus-i2c-devices-turris-omnia-mcu create mode 100644 Documentation/devicetree/bindings/arm/cznic,turris-omnia-mcu.yaml create mode 100644 drivers/platform/cznic/Kconfig create mode 100644 drivers/platform/cznic/Makefile create mode 100644 drivers/platform/cznic/turris-omnia-mcu-base.c create mode 100644 drivers/platform/cznic/turris-omnia-mcu-gpio.c create mode 100644 drivers/platform/cznic/turris-omnia-mcu-sys-off-wakeup.c create mode 100644 drivers/platform/cznic/turris-omnia-mcu-watchdog.c create mode 100644 drivers/platform/cznic/turris-omnia-mcu.h create mode 100644 include/linux/turris-omnia-mcu-interface.h
