From: Kory Maincent (Dent Project) <kory.maincent@xxxxxxxxxxx> 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 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@xxxxxxxxxxx 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@xxxxxxxxxxx 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@xxxxxxxxxxx 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@xxxxxxxxxxx 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@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 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 Signed-off-by: Kory Maincent <kory.maincent@xxxxxxxxxxx> --- Kory Maincent (17): MAINTAINERS: net: Add Oleksij to pse-pd maintainers of: property: Add fw_devlink support for pse parent net: pse-pd: Rectify and adapt the naming of admin_cotrol member of struct pse_control_config ethtool: Expand Ethernet Power Equipment with c33 (PoE) alongside PoDL net: pse-pd: Introduce PSE types enumeration net: ethtool: pse-pd: Expand pse commands with the PSE PoE interface netlink: specs: Modify pse attribute prefix netlink: specs: Expand the pse netlink command with PoE interface MAINTAINERS: Add myself to pse networking maintainer net: pse-pd: Add support for PSE PIs dt-bindings: net: pse-pd: Add another way of describing several PSE PIs net: pse-pd: Add support for setup_pi_matrix callback net: pse-pd: Use regulator framework within PSE framework dt-bindings: net: pse-pd: Add bindings for PD692x0 PSE controller net: pse-pd: Add PD692x0 PSE controller driver dt-bindings: net: pse-pd: Add bindings for TPS23881 PSE controller net: pse-pd: Add TI TPS23881 PSE controller driver .../bindings/net/pse-pd/microchip,pd692x0.yaml | 169 +++ .../bindings/net/pse-pd/pse-controller.yaml | 101 +- .../bindings/net/pse-pd/ti,tps23881.yaml | 95 ++ Documentation/netlink/specs/ethtool.yaml | 33 +- Documentation/networking/ethtool-netlink.rst | 20 + Documentation/networking/index.rst | 1 + Documentation/networking/pse-pd/index.rst | 10 + Documentation/networking/pse-pd/introduction.rst | 73 ++ Documentation/networking/pse-pd/pse-pi.rst | 302 +++++ MAINTAINERS | 8 + drivers/net/pse-pd/Kconfig | 20 + drivers/net/pse-pd/Makefile | 2 + drivers/net/pse-pd/pd692x0.c | 1223 ++++++++++++++++++++ drivers/net/pse-pd/pse_core.c | 513 +++++++- drivers/net/pse-pd/pse_regulator.c | 49 +- drivers/net/pse-pd/tps23881.c | 820 +++++++++++++ drivers/of/property.c | 2 + include/linux/pse-pd/pse.h | 83 +- include/uapi/linux/ethtool.h | 55 + include/uapi/linux/ethtool_netlink.h | 3 + net/ethtool/pse-pd.c | 60 +- 21 files changed, 3541 insertions(+), 101 deletions(-) --- base-commit: eae83f4ee41e2d65c136847bd8e93b837fb009a3 change-id: 20231024-feature_poe-139490e73403 Best regards, -- K�Maincent, Bootlin Embedded Linux and kernel engineering https://bootlin.com
