After doing some research, i found out that Fujitsu's hardware mointoring solution inside the SCH5627 exports data thru registers 0xA0 - 0xA3 regarding the mapping between temperature sensors and fans. If those registers are set to 0, the fans are forced to full speed. The first patch adds support for pwmX_auto_channels_temp attributes to the hwmon core, while the second patch does extend the sch5627 driver. Both patches have been tested on a Fujitsu Esprimo P720. --- Changes in v2: - acquire mutex before doing register reads/writes Armin Wolf (2): hwmon: (core) Add support for pwm auto channels attribute hwmon: (sch5627) Add pwmX_auto_channels_temp support Documentation/hwmon/sch5627.rst | 4 +++ drivers/hwmon/hwmon.c | 1 + drivers/hwmon/sch5627.c | 61 +++++++++++++++++++++++++++++++++ include/linux/hwmon.h | 2 ++ 4 files changed, 68 insertions(+) -- 2.30.2
