It would be best to have both tach feedbacks for this. Whatever the 
current driver interface that hwmon is using provides enough 
functionality for reading a single rotor's feedback along with being 
able to set a target speed to the fans currently. Because of this, I'd 
prefer that we focus on getting the dual tach feedback added and merge 
the complete driver then.

Thanks,
