It was mainly because the text talks about regulating currents and current rush, and an onboard ADC. There is admittedly even a bit of regulator framework-related business going on. On second look it's fine to keep as hwmon, discard my previous opinion, I should have looked closer and now I changed my mind. I'ts good with some pushback! Yours, Linus Walleij
