In the schematics for board rev 0.6 [0] I cannot find any information about a fan connector. The schematics for board rev 0.3 [1] on the other hand document a PWM based fan connector on page 16. So now I am not sure whether your patch only applies to certain board revisions, the schematics are incorrect, etc. Can you please provide some details about the fan connector on Odroid-N2/N2+ and which hardware revisions are supported (and which aren't) by your patch?
