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 Patch 6 depends on [1]. Changes since RFC v1 at [2]: - moved hwmon driver to thermal-only - moved the SM1 thermal nodes in a separate serie - added the bindings review tag from rob [1] http://lore.kernel.org/r/[email protected] [2] http://lore.kernel.org/r/[email protected] Neil Armstrong (6): dt-bindings: mfd: add Khadas Microcontroller bindings mfd: add support for the Khadas System control Microcontroller thermal: 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-khadas-vim3: add Khadas MCU nodes .../devicetree/bindings/mfd/khadas,mcu.yaml | 44 +++++ MAINTAINERS | 10 + .../boot/dts/amlogic/meson-khadas-vim3.dtsi | 23 +++ 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 +++++++++++++ drivers/thermal/Kconfig | 10 + drivers/thermal/Makefile | 1 + drivers/thermal/khadas_mcu_fan.c | 174 ++++++++++++++++++ include/linux/mfd/khadas-mcu.h | 91 +++++++++ 13 files changed, 649 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/khadas,mcu.yaml create mode 100644 drivers/mfd/khadas-mcu.c create mode 100644 drivers/nvmem/khadas-mcu-user-mem.c create mode 100644 drivers/thermal/khadas_mcu_fan.c create mode 100644 include/linux/mfd/khadas-mcu.h -- 2.22.0
