Subject: [PATCH net-next v9 00/14] net: Add support for Power over Ethernet
(PoE)
From: Kory Maincent (Dent Project) <kory.maincent@...tlin.com>
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.
3 patches has already been merged thanks to Jakub.
In detail:
- Patch 1 to 10 prepare net to support PoE devices.
- Patch 11 and 12 add PD692x0 PoE PSE controller driver and its binding.
- Patch 13 and 14 add TI TPS23881 PSE controller driver and its binding.
Changes in v9:
- Fix few kdoc return description missing.
- Fix a reference leak.
- Link to v8: https://lore.kernel.org/r/20240414-feature_poe-v8-0-e4bf1e860da5@bootlin.com
Changes in v8:
- Fix a build error due to an artifact from an ancient version of the
series.
- Link to v7: https://lore.kernel.org/r/20240409-feature_poe-v7-0-11e38efd4dee@bootlin.com
Changes in v7:
- Fix code, doc and kdoc nit.
- Fix few pd692x0 dt binding issues.
- Rename *flash_fw* functions to *flash_sram_fw* in tps23881 driver.
- Link to v6: https://lore.kernel.org/r/20240326-feature_poe-v6-0-c1011b6ea1cb@bootlin.com
Changes in v6:
- TPS23881 fix firmware management release missing.
- Use pcdev device pointer as regulator consumer and provider.
- Rename of_legacy to no_of_pse_pi.
- Add kdoc, and separate functions for better readability.
- Add vpwr-supply regulator parent.
- Link to v5: https://lore.kernel.org/r/20240227-feature_poe-v5-0-28f0aa48246d@bootlin.com
Changes in v5:
- Fix bindings nit.
- Add supported-polarity parameter to bindings.
- Fix yamllint binding errors.
- Remove the nested lock brought by the use of regulator framework.
- Link to v4: https://lore.kernel.org/r/20240215-feature_poe-v4-0-35bb4c23266c@bootlin.com
Changes in v4:
- Replaced sponsored-by tag by a simple sentence.
- Fix pse_pi node bindings.
- Add pse pi documentation written by Oleksij.
- Link to v3: https://lore.kernel.org/r/20240208-feature_poe-v3-0-531d2674469e@bootlin.com
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@bootlin.com
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@bootlin.com
