[PATCH net-next v3 00/17] net: Add support for Power over Ethernet (PoE)

From: Kory Maincent
Date: Thu Feb 08 2024 - 08:11:03 EST


This patch series aims at adding support for PoE (Power over Ethernet),
based on the already existing support for PoDL (Power over Data Line)
implementation. In addition, it adds support for two specific PoE
controller, the Microchip PD692x0 and the TI TPS23881.

In detail:
- Patch 1 to 13 prepare net to support PoE devices.
- Patch 14 and 15 add PD692x0 PoE PSE controller driver and its binding.
- Patch 16 and 17 add TI TPS23881 PSE controller driver and its binding.

Changes in v2:
- Extract "firmware_loader: Expand Firmware upload error codes patches" to
send it alone and get it merge in an immutable branch.
- Add "c33" prefix for PoE variables and enums.
- Enhance few comments.
- Add PSE Documentation.
- Make several changes in pd692x0 driver, mainly for readibility.
- Link to v1: https://lore.kernel.org/r/20231116-feature_poe-v1-0-be48044bf249@xxxxxxxxxxx

Changes in v3:
- Add patches to add Oleksij and myself to PSE MAINTAINERS.
- Add patches to add pse devlink.
- Add TI TPS23881 PSE controller driver with its binding.
- Replace pse_get_types helper by pse_has_podl and pse_has_c33
- Changed the PSE core bindings.
- Add a setup_pi_matrix callback.
- Register regulator for each PSE PI (Power Interface).
- Changed the PD692x0 bindings.
- Updated PD692x0 drivers to new bindings and PSE PI description.
- Updated PD692x0 drivers according to the reviews and made fixes.
- Link to v2: https://lore.kernel.org/r/20231201-feature_poe-v2-0-56d8cac607fa@xxxxxxxxxxx
