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**
