Subject: [PATCH v3 0/5] hwmon: pmbus: Add support for MPM82504 and MPM3695 family
Date: Sat, 10 May 2025 11:18:43 +0200 [thread overview]
Message-ID: <20250510091937.2298256-1-paweldembicki@gmail.com> (raw)
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.
