Changes in v5:
- Remove blank line in yaml header.
- Add interrupts property in yaml file.
- Uses a fallback compatible: infineon,tda38725 can be listed as a fallback for infineon,tda38740.
- Removed the driver-local identify callback and its duplicate VOUT_MODE check.
and set format[PSC_VOLTAGE_OUT] = linear in the static driver info.
- Dropped the per-device tda38740_data allocation/copy path, since there is no longer any runtime mutation of driver info.
Probe now passes the static tda38740_info directly to pmbus_do_probe().

Changes in v4:
- Fix the DT binding so that compatible only enumerates the valid
hardware variants and does not imply a preferred or fallback
selection policy.
- Remove the vout-scale-micro property and related code.
- Rename the example node to reflect the regulator function.
- Link to v3: https://lore.kernel.org/r/20260910-add-tda38740-and-tda38725-v3-0-3e87637da3d6@xxxxxxxxx
Changes in v3:
- Clarify that TDA38725 and TDA38740 share the same PMBus programming
model, with infineon,tda38740 as the preferred compatible string and
infineon,tda38725 as a compatibility alias.
- The optional VOUT scaling property with a documented default
value of 1.0 to support devices that require output-voltage scaling.
- Update the driver to apply the scaling for READ_VOUT.
- Link to v2: https://lore.kernel.org/r/20260907-add-tda38740-and-tda38725-v2-0-1d051d63aa01@xxxxxxxxx
Changes in v2:
- Use standard http:// URIs for $id and $schema
- Add maintainers section.
- Use C99 named initializers.
