Delta E50SN12051 is a 600W non-isolated 1/8th brick DC-DC power module.
With this series applied, voltage, current and temperature sensors can
be exposed through the standard hwmon interface.
Changes in this series:
- Introduce device-tree binding documentation for the new device
- Add hwmon documentation describing the supported sensors
- Add PMBus driver support for Delta E50SN12051

Changes in v3:
- Simplify to pass &e50sn12051_info directly to pmbus_do_probe()
to avoid the extra memory allocation
- Link to v2: https://lore.kernel.org/r/20260430-add-e50sn12051-v2-0-d76fe42482ab@xxxxxxxxx
Changes in v2:
- Add %YAML 1.2 declaration in binding document.
- Use a generic node name in examples in binding document.
- Add MODULE_IMPORT_NS("PMBUS")
- Remove unused / incorrect headers
- Link to v1: https://lore.kernel.org/r/20260429-add-e50sn12051-v1-0-c101e6c80bbb@xxxxxxxxx
