Subject: [PATCH v2 0/2] hwmon: (pmbus) Add support for MPS Multi-phase mp2856/mp2857 controller

Add support for mp2856/mp2857 device from Monolithic Power Systems, Inc.
(MPS) vendor. This is a dual-loop, digital, multi-phase,
modulation controller.

LINK: [v1] https://lore.kernel.org/all/20231108024222.2026546-1-peter.yin@quantatw.com/

changes v1 --> v2:
- mp2856.rst
  - fix wordings
- mp2856.c
  - fix register naming in defines
  - remove unused register defines
  - add max_phases and chip_id in struct mp2856_data
  - force vout in direct mode
  - remove unnecessary functions (ex: mp2856_identify_vid)
  - add identify multiphase for both rail1 and rail2

Peter Yin (2):
  dt-bindings: Add MP2856/MP2857 voltage regulator device
