[PATCH v2 0/5] hwmon: pmbus: Add support for MPM82504 and MPM3695 family

[Pawel Dembicki]

This series extends the hwmon PMBus driver for the MPS MPQ8785 to support
two additional Monolithic Power Systems devices: the MPM82504 and
MPM3695 family.

The driver is restructured to support multiple devices using device tree
matching. It also introduces an optional "mps,vout-fb-divider-ratio-permille"
property to configure the VOUT_SCALE_LOOP PMBus register, which adjusts
reported output voltages depending on the external feedback divider.

Device tree bindings are updated accordingly.

Changes have been tested on hardware with device-tree based matching
using the MPM82504 and MPM3695-10.
