21 This driver implements support for the Microchip LAN9668 on-chip
22 temperature sensor as well as its fan controller. It provides one
23 temperature sensor and one fan controller. The temperature range
24 of the sensor is specified from -40 to +125 degrees Celsius and
25 its accuracy is +/- 5 degrees Celsius. The fan controller has a
26 tacho input and a PWM output with a customizable PWM output
27 frequency ranging from ~20Hz to ~650kHz.
29 No alarms are supported by the SoC.
31 The driver exports temperature values, fan tacho input and PWM
32 settings via the following sysfs files:
