The new Khadas VIM2, VIM3 and Edge boards embeds an on-board microcontroller connected via I2C. This Microcontroller is present on the Khadas VIM1, VIM2, VIM3 and Edge boards. It has multiple boot control features like password check, power-on options, power-off control and system FAN control on recent boards. Thie serie adds : - the bindings - the MFD driver - the HWMON cell driver - the NVMEM cell driver - updates MAINTAINERS - add support into the Khadas VIM3/VIM3L DT Neil Armstrong (8): dt-bindings: mfd: add Khadas Microcontroller bindings mfd: add support for the Khadas System control Microcontroller hwmon: add support for the MCU controlled FAN on Khadas boards nvmem: add support for the Khadas MCU Programmable User Memory MAINTAINERS: add myself as maintainer for Khadas MCU drivers arm64: dts: meson-g12b: move G12B thermal nodes to meson-g12b.dtsi arm64: dts: meson-sm1: add cpu thermal nodes arm64: dts: meson-khadas-vim3: add Khadas MCU nodes .../devicetree/bindings/mfd/khadas,mcu.yaml | 44 ++++ MAINTAINERS | 11 + arch/arm64/boot/dts/amlogic/meson-g12.dtsi | 23 -- arch/arm64/boot/dts/amlogic/meson-g12b.dtsi | 22 ++ .../boot/dts/amlogic/meson-khadas-vim3.dtsi | 23 ++ arch/arm64/boot/dts/amlogic/meson-sm1.dtsi | 24 ++ drivers/hwmon/Kconfig | 9 + drivers/hwmon/Makefile | 1 + drivers/hwmon/khadas-mcu-fan.c | 230 ++++++++++++++++++ drivers/mfd/Kconfig | 14 ++ drivers/mfd/Makefile | 1 + drivers/mfd/khadas-mcu.c | 143 +++++++++++ drivers/nvmem/Kconfig | 8 + drivers/nvmem/Makefile | 2 + drivers/nvmem/khadas-mcu-user-mem.c | 128 ++++++++++ include/linux/mfd/khadas-mcu.h | 91 +++++++ 16 files changed, 751 insertions(+), 23 deletions(-) create mode 100644 Documentation/devicetree/bindings/mfd/khadas,mcu.yaml create mode 100644 drivers/hwmon/khadas-mcu-fan.c create mode 100644 drivers/mfd/khadas-mcu.c create mode 100644 drivers/nvmem/khadas-mcu-user-mem.c create mode 100644 include/linux/mfd/khadas-mcu.h -- 2.22.0
