Zev Weiss	08da09f028	hwmon: (pmbus) delta-ahe50dc-fan: work around hardware quirk ... CLEAR_FAULTS commands can apparently sometimes trigger catastrophic power output glitches on the ahe-50dc, so block them from being sent at all.

Zev Weiss	d387d88ed0	hwmon: (pmbus) Add Delta AHE-50DC fan control module driver ... This device is an integrated module of the Delta AHE-50DC Open19 power shelf. I haven't been able to procure any proper documentation for it, but it seems to be a (somewhat minimally) PMBus-compliant device. It provides four fan speeds, four temperatures (three standard and one manufacturer-specific via a virtual second page), and a vin reading.
