I have a system that has very over spec'd fans so the amount of noise when they run at 100% duty cycle is considerable. We have userspace monitoring tools that will configure appropriate fan control parameters but there is a bit of a delay between the kernel loading the driver and the userland tools catching up to configure the fan control. This series adds device properties that allow the PWM duty cycle to be specified via device properties so the PWM duty cycle can be reduced as soon as possible.
