Subject: [PATCH net-next 0/9] net: Add support for Power over Ethernet (PoE)
Date: Thu, 16 Nov 2023 15:01:32 +0100	[thread overview]
Message-ID: <20231116-feature_poe-v1-0-be48044bf249@bootlin.com> (raw)

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.

In detail:
- Patch 1 to 6 prepare net to support PoE devices.
- Patch 7 adds a new error code to firmware upload API.
- Patch 8 and 9 add PD692x0 PoE PSE controller driver and its binding.
