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**
