|
------------
|
||
|
|
This driver implements support for ASPEED AST2400/2500 PWM and Fan Tacho
|
||
|
|
controller. The PWM controller supports up to 8 PWM outputs. The Fan tacho
|
||
|
|
controller supports up to 16 tachometer inputs.

|
|
by the fan to the device.
|
||
|
|
|
||
|
|
pwmX rw get or set PWM fan control value. This is an integer
