Kernel driver lan966x-hwmon¶
Microchip LAN9668 (sensor in SoC)
Michael Walle <email@example.com>
This driver implements support for the Microchip LAN9668 on-chip temperature sensor as well as its fan controller. It provides one temperature sensor and one fan controller. The temperature range of the sensor is specified from -40 to +125 degrees Celsius and its accuracy is +/- 5 degrees Celsius. The fan controller has a tacho input and a PWM output with a customizable PWM output frequency ranging from ~20Hz to ~650kHz.
No alarms are supported by the SoC.
The driver exports temperature values, fan tacho input and PWM settings via the following sysfs files:
