Changes since v11: - fixed some includes, suggested by Andy - moved #include after the other includes, since it is domain specific, suggested by Andy - in patch 2, use sizeof() of dest buffer in memcpy call, instead of ETH_ALEN constant, as suggested by Andy - in patch 3, dropped the .has_int member of omnia GPIO definition structure, and added is_int_bit_valid() function instead, as suggested by Andy - in patch 3, changed int to unsigned int where appropriate, as suggested by Andy - in patch 3, fixed docstring indentation, suggested by Andy - in patch 4 dropped #include , and instead declared struct rtc_device, it is only used as a pointer, suggested by Andy - in patch 5, renamed the completion from trng_completion to trng_entropy_available - in patch 5, use gpio_device_get_desc() instead of gpiochip_get_desc() when mapping IRQ (as discussed with Andy and Bart) - in patch 5, dropped setting the priv member of hwrng, and instead use container_of() to get the driver private structure, suggested by Herbert Links to previous cover letters (v1 to v11): https://patchwork.kernel.org/project/linux-soc/cover/20230823161012.6986-1-kabel@kernel.org/ https://patchwork.kernel.org/project/linux-soc/cover/20230919103815.16818-1-kabel@kernel.org/ https://patchwork.kernel.org/project/linux-soc/cover/20231023143130.11602-1-kabel@kernel.org/ https://patchwork.kernel.org/project/linux-soc/cover/20231026161803.16750-1-kabel@kernel.org/ https://patchwork.kernel.org/project/linux-soc/cover/20240323164359.21642-1-kabel@kernel.org/ https://patchwork.kernel.org/project/linux-soc/cover/20240418121116.22184-1-kabel@kernel.org/ https://patchwork.kernel.org/project/linux-soc/cover/20240424173809.7214-1-kabel@kernel.org/ https://patchwork.kernel.org/project/linux-soc/cover/20240430115111.3453-1-kabel@kernel.org/ https://patchwork.kernel.org/project/linux-soc/cover/20240508103118.23345-1-kabel@kernel.org/ https://patchwork.kernel.org/project/linux-soc/cover/20240510101819.13551-1-kabel@kernel.org/ https://patchwork.kernel.org/project/linux-soc/cover/20240605161851.13911-1-kabel@kernel.org/ Marek Behún (8): dt-bindings: firmware: 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 platform: cznic: turris-omnia-mcu: Add support for MCU provided TRNG 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 | 113 ++ .../firmware/cznic,turris-omnia-mcu.yaml | 86 ++ MAINTAINERS | 4 + .../dts/marvell/armada-385-turris-omnia.dts | 35 +- drivers/platform/Kconfig | 2 + drivers/platform/Makefile | 1 + drivers/platform/cznic/Kconfig | 48 + drivers/platform/cznic/Makefile | 8 + .../platform/cznic/turris-omnia-mcu-base.c | 408 +++++++ .../platform/cznic/turris-omnia-mcu-gpio.c | 1088 +++++++++++++++++ .../cznic/turris-omnia-mcu-sys-off-wakeup.c | 260 ++++ .../platform/cznic/turris-omnia-mcu-trng.c | 103 ++ .../cznic/turris-omnia-mcu-watchdog.c | 130 ++ drivers/platform/cznic/turris-omnia-mcu.h | 194 +++ include/linux/turris-omnia-mcu-interface.h | 249 ++++ 15 files changed, 2728 insertions(+), 1 deletion(-) create mode 100644 Documentation/ABI/testing/sysfs-bus-i2c-devices-turris-omnia-mcu create mode 100644 Documentation/devicetree/bindings/firmware/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-trng.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
