Description

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:

temp1_input

fan1_input

pwm1

pwm1_freq
