Hello, These patches add a hwmon driver for the integrated fan control module in the Delta AHE-50DC Open19 power shelf. I don't know of a datasheet any proper documentation for it; the register layout information came from an existing GPL driver [0] in a code release from LinkedIn. Thanks, Zev Weiss [0] https://github.com/linkedin/o19-bmc-firmware/blob/master/meta-openbmc/meta-linkedin/meta-deltapower/recipes-kernel/fancontrol-mod/files/fancontrol.c Zev Weiss (2): hwmon: add Delta AHE-50DC fan control module driver dt-bindings: add Delta AHE-50DC fan control module .../devicetree/bindings/trivial-devices.yaml | 2 + MAINTAINERS | 6 + drivers/hwmon/Kconfig | 11 + drivers/hwmon/Makefile | 1 + drivers/hwmon/delta-ahe50dc-fan.c | 265 ++++++++++++++++++ 5 files changed, 285 insertions(+) create mode 100644 drivers/hwmon/delta-ahe50dc-fan.c -- 2.34.1
