[PATCH v3 0/2] Support RAA229639 and RAA229640

Changes in v3:
- Updated the OF match entries for renesas,raa229639 and renesas,raa229640 to use 
  raa_dmpvr2_2rail_nontc instead of raa_dmpvr2_2rail.
- Compatible with existing 2-rail non-TC controllers and use renesas,raa228244 
  as fallback compatible.
- Link to v2: https://lore.kernel.org/r/20260908-add-raa229639-and-raa229640-v2-0-83c75b61139d@gmail.com

Changes in v2:
- Clarify why fallback compatibles are not added in the DT binding.
- Reword driver commit message to avoid implying DT-level compatibility.
- Link to v1: https://lore.kernel.org/r/20260907-add-raa229639-and-raa229640-v1-0-8f7218cba85d@gmail.com

[PATCH v3 1/2] dt-bindings: hwmon: pmbus: isl68137: Add Renesas RAA229639 and RAA229640

[Colin Huang]

Add Device Tree compatible strings for Renesas RAA229639 and
RAA229640 PMBus devices.

They are compatible with existing 2-rail non-TC controllers
and use renesas,raa228244 as fallback compatible

[PATCH v3 2/2] hwmon: (pmbus/isl68137): Add Renesas RAA229639 and RAA229640

[Colin Huang]

Add support for the Renesas RAA229639 and RAA229640 PMBus
voltage regulator devices.

Both devices are supported by the existing raa_dmpvr2_2rail_nontc
driver variant, so no functional changes are required beyond
adding the corresponding device IDs and OF match entries.

The entire point of fallback is to avoid this change. Why do you need
this?

I personally like to have it for this driver because it makes it easy to
track which device require which configuration without having to track down
devicetree fallbacks.
