Supported chips:
* Microchip LAN9668 (sensor in SoC)
Prefix: 'lan9668-hwmon'

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:
