[PATCH v3 0/2] hwmon: (pmbus/lm25066) Support SMBus Current Limit configuration

[Potin Lai <potin.lai.pt@gmail.com>]

This series adds support for configuring the current limit behavior via
software override on LM25066-compatible devices (excluding LM25056) using
the DEVICE_SETUP (0xD9) register.

When the 'ti,current-range' property is specified in the device tree,
the driver configures the DEVICE_SETUP register's Current Limit Configuration
bit (bit 2) to activate SMBus/software override and sets the Current Limit

Setting bit (bit 4) to "low" or "high" threshold accordingly.
Since LM25056 does not support software override (bit 2 of DEVICE_SETUP is
reserved), it is explicitly excluded from this support in both the device
tree binding schema and the driver.

---
Changes in v3:
- Renamed property from 'ti,current-limit' to 'ti,current-range' to
  resolve the global schema type conflict.
- Updated commit messages and bindings description to document supported
  devices and their physical voltage mappings for the low/high settings.
- Link to v2: https://patch.msgid.link/20260615-lm25066-cl-config-v2-0-59be46e67d5a@gmail.com

Changes in v2:
- Replaced the boolean properties ('ti,cl-smbus-high' and 'ti,cl-smbus-low')
  with a single string property 'ti,current-limit' ('low' or 'high')
- Excluded lm25056 in the driver from parsing/setting the current limit property.
- Link to v1: https://patch.msgid.link/20260611-lm25066-cl-config-v1-0-02e567bf3d91@gmail.com
