This driver implements support for the Nuvoton NCT7802Y hardware monitoring chip. NCT7802Y supports 6 temperature sensors, 5 voltage sensors, and 3 fan speed sensors.
Smart Fan™ speed control is available via pwmX_auto_point attributes.
Sysfs attributes unique to this chip are documented below. For common attributes, see Documentation/hwmon/sysfs-interface.rst.
step_up_time Time interval between successive duty cycle increases when in Smart Fan mode. Specified in milliseconds and rounded to intervals of 100 in the range 100-25500.
step_down_time Time interval between successive duty cycle decreases when in Smart Fan mode. Specified in milliseconds and rounded to intervals of 100 in the range 100-25500.
The driver has been reported to work with the following boards and BIOS versions.
