> I agree. But the chip also has led functionality. I got review feedback to make it MFD. So when rewriting as MFD driver made separate driver based on subsystem. I'm not sure if it is ok to use hwmon subsytem in regulator driver. Will once check with maintainer on this.

LED has completely different functionality. Overlap between regulator and
hwmon is substantial because the regulator code handles limits and alarms.
Sure, you kind of bypassed (ignored) that by not implementing limit and alarm
support in the hwmon driver, but that is really just avoiding the problem,
not solving it.
