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 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 dt-bindings: net: pse-pd: Add another way of describing several PSE PIs net: pse-pd: Add support for 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 | 157 +++ .../bindings/net/pse-pd/pse-controller.yaml | 101 +- .../bindings/net/pse-pd/ti,tps2388x.yaml | 112 ++ Documentation/netlink/specs/ethtool.yaml | 33 +- Documentation/networking/ethtool-netlink.rst | 20 + Documentation/networking/index.rst | 1 + Documentation/networking/pse-pd/index.rst | 9 + Documentation/networking/pse-pd/introduction.rst | 73 ++ MAINTAINERS | 8 + drivers/net/mdio/fwnode_mdio.c | 29 +- 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 | 491 +++++++- drivers/net/pse-pd/pse_regulator.c | 49 +- drivers/net/pse-pd/tps23881.c | 818 +++++++++++++ drivers/of/property.c | 2 + include/linux/pse-pd/pse.h | 89 +- include/uapi/linux/ethtool.h | 43 + include/uapi/linux/ethtool_netlink.h | 3 + include/uapi/linux/pse.h | 23 + net/ethtool/pse-pd.c | 60 +- 22 files changed, 3246 insertions(+), 120 deletions(-) --- base-commit: 05f5c48cfac2335df9bb76fb6d49703670ce8b00 change-id: 20231024-feature_poe-139490e73403 Best regards, -- Köry Maincent, Bootlin Embedded Linux and kernel engineering https://bootlin.com
