Description:¶
This driver implements support for ASPEED AST2400/2500 PWM and Fan Tacho controller. The PWM controller supports upto 8 PWM outputs. The Fan tacho controller supports up to 16 tachometer inputs.
The driver provides the following sensor accesses in sysfs:
fanX_input |
ro |
provide current fan rotation value in RPM as reported by the fan to the device. |
pwmX |
rw |
get or set PWM fan control value. This is an integer value between 0(off) and 255(full speed). |
