[PATCH v2 0/2] hwmon: (pmbus/max20830) add MAX20810/15 and LTM4739/40

[Carlos Jones <carlosjr.jones@analog.com>]

From: Carlos Jones Jr <carlosjr.jones@analog.com>

This series adds support for four additional members of the MAX20830
PMBus regulator family to the existing max20830 driver:

  - MAX20810 (10A) and MAX20815 (15A)
  - LTM4739 and LTM4740, the LTM-series module equivalents of the
    MAX20810 and MAX20815 respectively

All four share the MAX20830 PMBus command set and telemetry, so support
amounts to accepting their IC_DEVICE_ID and documenting the parts; no new
register handling is required. The LTM4739/LTM4740 modules are built around
the MAX20810/MAX20815 dies and report the die's IC_DEVICE_ID ("MAX20810B" /
"MAX20815B"), which the driver matches at probe. Device-tree matching uses
the existing adi,max20830 fallback compatible, so no new of_match entries
are needed.

Patch 1 adds the device-tree binding compatibles; patch 2 adds the driver
support and documentation.

Changes since v1:
- Document the IC_DEVICE_ID vs datasheet discrepancy in-tree, per Guenter's
  review: a code comment above supported_chip_ids[] and an expanded commit
  message, including why the plain datasheet IDs ("MAX20810"/"MAX20815"/
  "LTM4739"/"LTM4740") are not matched (no hardware reporting them observed).
- Rebased on current hwmon-next; no functional change.
- Patch 1 (dt-bindings) is unchanged and carries Conor Dooley's Acked-by
  from v1.
