Two of the SERDES6G support QSGMII. + Also it has 8 logical Ethernet ports which can be connected to these + interfaces. The Serdes controller will allow to configure these interfaces + and allows to "mux" the interfaces to different ports. + + For simple selection of the interface that is used with a port, the + following macros are defined CU(X), SERDES6G(X), RGMII(X). Where X is a + number that represents the index of that interface type. For example + CU(1) means use interface copper transceivers 1. SERDES6G(2) means use + interface SerDes 2. + +properties: + $nodename: + pattern: "^serdes@[0-9a-f]+$" + + compatible: + const: microchip,lan966x-serdes + + reg: + items: + - description: HSIO registers + - description: HW_STAT register + + '#phy-cells': + const: 2 + description: | + - Input port to use for a given macro. + - The macro to be used.
