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 Thermal Cooling cell driver - add support into the Khadas VIM3/VIM3L DT Changes since v3 at [4]: - Removed Applied patches 1, 2 & 4 - Added reviewed-by tags for patch 3 & 5 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/20200512093916.19676-1-narmstrong@baylibre.com [2] http://lore.kernel.org/r/20200421080102.22796-1-narmstrong@baylibre.com [3] http://lore.kernel.org/r/20200512132613.31507-1-narmstrong@baylibre.com [4] http://lore.kernel.org/r/20200608091739.2368-1-narmstrong@baylibre.com Neil Armstrong (2): thermal: add support for the MCU controlled FAN on Khadas boards arm64: dts: meson-khadas-vim3: add Khadas MCU nodes .../boot/dts/amlogic/meson-khadas-vim3.dtsi | 23 +++ drivers/thermal/Kconfig | 11 ++ drivers/thermal/Makefile | 1 + drivers/thermal/khadas_mcu_fan.c | 174 ++++++++++++++++++ 4 files changed, 209 insertions(+) create mode 100644 drivers/thermal/khadas_mcu_fan.c
