[PATCH 0/3] hwmon: (pmbus/max34440): Bug fixes and supporting new device

From: Alexis Czezar Torreno

Date: Thu Jul 16 2026 - 04:28:41 EST


This series fixes register access issues in MAX34451/ADPM devices and adds
support for newer MAX34451 variants and the MAX34452 device.

The first patch addresses an issue where the driver attempts to access
unsupported registers on MAX34451 and ADPM devices, causing CML errors and
triggering ALERT.

The second patch adds support for the newer MAX34451ETNA8+ silicon revision
which uses different direct format coefficients for voltage and current
measurements.

The third patch introduces support for the MAX34452, a 16-channel voltage/
current monitor that shares a similar architecture with MAX34451.
