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 Thermal Cooling cell driver - updates MAINTAINERS - add support into the Khadas VIM3/VIM3L DT Changes since v2 at [3]: - Removed NVMEM driver for separate submission - fixed MFD driver, header and Kconfig - fixed Thermal Kconfig - fixed MAINTAINERS files and path 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] [3] http://lore.kernel.org/r/[email protected] Neil Armstrong (5): 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 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 | 9 + .../boot/dts/amlogic/meson-khadas-vim3.dtsi | 23 +++ drivers/mfd/Kconfig | 21 +++ drivers/mfd/Makefile | 1 + drivers/mfd/khadas-mcu.c | 142 ++++++++++++++ drivers/thermal/Kconfig | 11 ++ drivers/thermal/Makefile | 1 + drivers/thermal/khadas_mcu_fan.c | 174 ++++++++++++++++++ include/linux/mfd/khadas-mcu.h | 91 +++++++++ 10 files changed, 517 insertions(+) create mode 100644 Documentation/devicetree/bindings/mfd/khadas,mcu.yaml create mode 100644 drivers/mfd/khadas-mcu.c create mode 100644 drivers/thermal/khadas_mcu_fan.c create mode 100644 include/linux/mfd/khadas-mcu.h -- 2.22.0
