|
||
|
|
This driver implements support for ASPEED AST2600 Fan Tacho controller.
|
||
|
|
The controller supports up to 16 tachometer inputs.
|

=============== ======= ======================================================
|

|
|
fanX_input ro provide current fan rotation value in RPM as reported
|
||
|
|
by the fan to the device.
|
||
|
|
fanX_div rw Fan divisor: Supported value are power of 4 (1, 4, 16
|
||
|
|
64, ... 4194304)
|
||
|

|
|
affected by fan signal glitch.
