+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 2.
+ The first number defines the input port to use for a given
+ SerDes macro. The second defines the macro to use. They are
+ defined in dt-bindings/phy/phy-ocelot-serdes.h
+
+Example:
+
+ serdes: serdes {
+ compatible = "mscc,vsc7514-serdes";
+ #phy-cells = <2>;
+ };
+
+ ethernet {
+ port1 {
+ phy-handle = <&phy_foo>;
+ /* Link SERDES1G_5 to port1 */
+ phys = <&serdes 1 SERDES1G_5>;
+ };
+ };
