Subject: [PATCH v3 1/4] dt-bindings: soc: Add bindings for Airoha SCU Serdes lines
Date: Wed, 29 Oct 2025 18:37:09 +0100 [thread overview]
Message-ID: <20251029173713.7670-2-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20251029173713.7670-1-ansuelsmth@gmail.com>
The Airoha AN7581 SoC can configure the SCU serdes lines for multiple
purpose. For example the Serdes for the USB1 port can be both
used for USB 3.0 operation or for Ethernet. Or the USB2 serdes can both
used for USB 3.0 operation or for PCIe.
The PCIe Serdes can be both used for PCIe operation or for Ethernet.
Add bindings to permit correct reference of the different ports in DT,
mostly to differentiate the different supported modes internally to the
drivers.
