Subject: [PATCH 04/10] dt-bindings: soc: Add bindings for Airoha SCU Serdes
|
|
lines
|
|
|
|
The Airoha AN7581 SoC have 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.
|
|
|
|
Add bindings to permit correct reference of the different ports in DT,
|
|
mostly to differenciate the different supported modes internally to the
|
|
drivers.
