Subject: [PATCH net-next 00/14] Arrange PSE core and update TPS23881 driver

From: Kory Maincent (Dent Project) <kory.maincent@...tlin.com>

This patch includes several improvements to the PSE core for better
implementation and maintainability:

- Move the conversion between current limit and power limit from the driver
  to the PSE core.
- Update power and current limit checks.
- Split the ethtool_get_status callback into multiple callbacks.
- Add support for PSE device index.
- Fix PSE PI of_node detection.

Additionally, the TPS23881 driver has been updated to support power
limit and measurement features, aligning with the new PSE core
functionalities.

This patch series is the first part of the budget evaluation strategy
support patch series sent earlier:
