This adds a driver for the temperature sensor on the JH7100, a RISC-V SoC by StarFive Technology Co. Ltd., and most likely also the upcoming JH7110 version. The SoC is used on the BeagleV Starlight board: https://github.com/beagleboard/beaglev-starlight Support for this SoC is not yet upstreamed, but is actively worked on, so it should only be a matter of time before that happens. v3: * Handle timeouts from wait_for_completion_interruptible_timeout properly. v2: * Fix checkpatch.pl --strict warnings - Add myself to MAINTAINERS - Fix multiline comments - Use proper case and whitespace for #defines - Add comment to sfctemp::lock mutex. * Remaining comments by Guenter Roeck - Add Documentation/hwmon/sfctemp.rst - Use devm_add_action() and devm_hwmon_device_register_with_info() instead of a driver .remove function. - Don't do test conversion at probe time. - #include <linux/io.h> - Remove unused #defines - Use int return variable in sfctemp_convert(). * Add Samin's Signed-off-by to patch 2/2 Emil Renner Berthing (2): dt-bindings: hwmon: add starfive,jh7100-temp bindings hwmon: (sfctemp) Add StarFive JH7100 temperature sensor .../bindings/hwmon/starfive,jh7100-temp.yaml | 43 +++ Documentation/hwmon/index.rst | 1 + Documentation/hwmon/sfctemp.rst | 32 ++ MAINTAINERS | 8 + drivers/hwmon/Kconfig | 10 + drivers/hwmon/Makefile | 1 + drivers/hwmon/sfctemp.c | 291 ++++++++++++++++++ 7 files changed, 386 insertions(+) create mode 100644 Documentation/devicetree/bindings/hwmon/starfive,jh7100-temp.yaml create mode 100644 Documentation/hwmon/sfctemp.rst create mode 100644 drivers/hwmon/sfctemp.c -- 2.32.0
