Subject: [PATCH net-next 2/4] dt-bindings: net: ethernet-controller: add QUSGMII mode
Date: Thu, 28 Jul 2022 16:52:50 +0200 [thread overview]
Message-ID: <20220728145252.439201-3-maxime.chevallier@bootlin.com> (raw)
In-Reply-To: <20220728145252.439201-1-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.
