Not support FAN dual rotator to one present pin
Hi All,
I am working on to add dual-rotor fans in my BMC. I added the below code. But the Fan_#_b does not have present property(cause of the present pin could use only one) , it will trigger the under threshold event due to no present judgment.
How do support dual-rotor in same present pin?
