What is it hooked up to to measure? You only mention "fan" five times in the doc. You have #pwm-cells too, so this block has PWM output as well? If not, then where's the PWM for the fan control because there is no point in having fan tach without some control mechanism. There's only so many ways to control fans and types of fans, so yes, the interface of control and feedback lines between a fan and its controller should absolutely be generic.
