[PATCH net-next v2 0/8] net: pse-pd: Add new PSE c33 features

[Kory Maincent <kory.maincent@bootlin.com>]

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

This patch series adds new c33 features to the PSE API.
- Expand the PSE PI informations status with power, class and failure
  reason
- Add the possibility to get and set the PSE PIs power limit

Jakub could you check if patchwork works correctly with this patch series.

Changes in v2:
- Use uA and uV instead of mA and mV to have more precision in the power
  calculation. Need to use 64bit variables for the calculation.
- Modify the pd-92x0behavior in case of setting the current out of the
  available ranges. Report an error now.
- Link to v1: https://lore.kernel.org/r/20240529-feature_poe_power_cap-v1-0-0c4b1d5953b8@bootlin.com
