    +Microsemi Ocelot SerDes muxing driver
    +-------------------------------------
    +
    +On Microsemi Ocelot, there is a handful of registers in HSIO address
    +space for setting up the SerDes to switch port muxing.
    +
    +A SerDes X can be "muxed" to work with switch port Y or Z for example.
    +One specific SerDes can also be used as a PCIe interface.
    +
    +Hence, a SerDes represents an interface, be it an Ethernet or a PCIe one.
    +
    +There are two kinds of SerDes: SERDES1G supports 10/100Mbps in
    +half/full-duplex and 1000Mbps in full-duplex mode while SERDES6G supports
    +10/100Mbps in half/full-duplex and 1000/2500Mbps in full-duplex mode.
    +
    +Also, SERDES6G number (aka "macro") 0 is the only interface supporting
    +QSGMII.
    +
    +Required properties:
    +
    +- compatible: should be "mscc,vsc7514-serdes"
    +- #phy-cells : from the generic phy bindings, must be 3. The first number
    + defines the kind of Serdes (1 for SERDES1G_X, 6 for
    + SERDES6G_X), the second defines the macros in the specified
    + kind of Serdes (X for SERDES1G_X or SERDES6G_X) and the
    + last one defines the input port to use for a given SerDes
    + macro,
    +
    +Example:
    +
    + serdes: serdes {
    + compatible = "mscc,vsc7514-serdes";
    + #phy-cells = <3>;
    + };
    +
    + ethernet {
    + port1 {
    + phy-handle = <&phy_foo>;
    + /* Link SERDES1G_5 to port1 */
    + phys = <&serdes 1 5 1>;
    + };
    + };
