I dunno. iio-hwmon to me is a particularly strange one, because it is the exact same device being used in different subsystems. Like that voltage monitoring device with 10000 compatibles that I CCed you and Peter on the other day feels like it should really in your subsytem. A "hwmon" isn't a class of device at all. This however, I think is more like pwm-clock (or clk-pwm, they both exist and are opposites) where the node is used to change the type of device rather than the subsystem using it. > So this one may need more explanation and justification and I'd definitely > like some DT maintainer review on this at a fairly early stage! Ye, /shrug. Maybe the others have dissenting opinions. I'd like to hear from them, but I don't personally have a problem with this.
