14 On Microsemi Ocelot, there is a handful of registers in HSIO address
15 space for setting up the SerDes to switch port muxing.
16
17 A SerDes X can be "muxed" to work with switch port Y or Z for example.
18 One specific SerDes can also be used as a PCIe interface.
19
20 Hence, a SerDes represents an interface, be it an Ethernet or a PCIe one.
21
22 There are two kinds of SerDes: SERDES1G supports 10/100Mbps in
23 half/full-duplex and 1000Mbps in full-duplex mode while SERDES6G supports
24 10/100Mbps in half/full-duplex and 1000/2500Mbps in full-duplex mode.
25
26 Also, SERDES6G number (aka "macro") 0 is the only interface supporting
27 QSGMII.
28
29 This is a child of the HSIO syscon ("mscc,ocelot-hsio", see
30 Documentation/devicetree/bindings/mips/mscc.txt) on the Microsemi Ocelot.
