Kernel driver aspeed-pwm-tacho
Supported chips:
ASPEED AST2400/2500
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.
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).
