Subject: [PATCH net-next v4 2/4] dt-bindings: net: ethernet-controller: add QUSGMII mode
Date: Mon,  1 Aug 2022 09:37:11 +0200	[thread overview]
Message-ID: <20220801073713.32290-3-maxime.chevallier@bootlin.com> (raw)
In-Reply-To: <20220801073713.32290-1-maxime.chevallier@bootlin.com>

Add a new QUSGMII mode, standing for "Quad Universal Serial Gigabit
Media Independent Interface", a derivative of USGMII which, similarly to
QSGMII, allows to multiplex 4 1Gbps links to a Quad-PHY.

The main difference with QSGMII is that QUSGMII can include an extension
instead of the standard 7bytes ethernet preamble, allowing to convey
arbitrary data such as Timestamps.
