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 one specific PoE controller, the Microchip PD692x0. The PD692x0 driver is based on the patch merged in an immutable branch from Jakub repo. It is Tagged at: git://git.kernel.org/pub/scm/linux/kernel/git/kuba/linux.git firmware_loader-add-upload-error The patch is already merged in net-next. In detail: - Patch 1 to 6 prepare net to support PoE devices. - Patch 7 and 8 add PD692x0 PoE 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 Signed-off-by: Kory Maincent <kory.maincent@xxxxxxxxxxx> --- Kory Maincent (8): 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 dt-bindings: net: pse-pd: Add bindings for PD692x0 PSE controller net: pse-pd: Add PD692x0 PSE controller driver .../bindings/net/pse-pd/microchip,pd692x0.yaml | 77 ++ Documentation/netlink/specs/ethtool.yaml | 33 +- Documentation/networking/ethtool-netlink.rst | 20 + Documentation/networking/pse-pd/introduction.rst | 73 ++ MAINTAINERS | 7 + drivers/net/pse-pd/Kconfig | 11 + drivers/net/pse-pd/Makefile | 1 + drivers/net/pse-pd/pd692x0.c | 1025 ++++++++++++++++++++ drivers/net/pse-pd/pse_core.c | 9 + drivers/net/pse-pd/pse_regulator.c | 9 +- include/linux/pse-pd/pse.h | 35 +- include/uapi/linux/ethtool.h | 43 + include/uapi/linux/ethtool_netlink.h | 3 + net/ethtool/pse-pd.c | 64 +- tools/net/ynl/generated/ethtool-user.c | 54 +- tools/net/ynl/generated/ethtool-user.h | 81 +- 16 files changed, 1481 insertions(+), 64 deletions(-) --- base-commit: 98137c429a4854583210707a82114b4f5c171c5e change-id: 20231024-feature_poe-139490e73403 Best regards, -- Köry Maincent, Bootlin Embedded Linux and kernel engineering https://bootlin.com
