-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.
-
-This is a child of the HSIO syscon ("mscc,ocelot-hsio", see
-Documentation/devicetree/bindings/mips/mscc.txt) on the Microsemi Ocelot.
-
-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

-Example:

- #phy-cells = <2>;
- };
-
- ethernet {
- port1 {
- phy-handle = <&phy_foo>;
- /* Link SERDES1G_5 to port1 */
- phys = <&serdes 1 SERDES1G_5>;

-* Renesas R-Car generation 2 USB PHY
-
-This file provides information on what the device node for the R-Car generation
-2 USB PHY contains.
-
-Required properties:
-- compatible: "renesas,usb-phy-r8a7742" if the device is a part of R8A7742 SoC.
- "renesas,usb-phy-r8a7743" if the device is a part of R8A7743 SoC.
- "renesas,usb-phy-r8a7744" if the device is a part of R8A7744 SoC.
- "renesas,usb-phy-r8a7745" if the device is a part of R8A7745 SoC.
- "renesas,usb-phy-r8a77470" if the device is a part of R8A77470 SoC.
- "renesas,usb-phy-r8a7790" if the device is a part of R8A7790 SoC.
- "renesas,usb-phy-r8a7791" if the device is a part of R8A7791 SoC.
- "renesas,usb-phy-r8a7794" if the device is a part of R8A7794 SoC.
- "renesas,rcar-gen2-usb-phy" for a generic R-Car Gen2 or
- RZ/G1 compatible device.
-
- When compatible with the generic version, nodes must list the
- SoC-specific version corresponding to the platform first
- followed by the generic version.
-
-- reg: offset and length of the register block.
-- #address-cells: number of address cells for the USB channel subnodes, must
- be <1>.
-- #size-cells: number of size cells for the USB channel subnodes, must be <0>.
-- clocks: clock phandle and specifier pair.
-- clock-names: string, clock input name, must be "usbhs".
-
-The USB PHY device tree node should have the subnodes corresponding to the USB
-channels. These subnodes must contain the following properties:
-- reg: the USB controller selector; see the table below for the values.
-- #phy-cells: see phy-bindings.txt in the same directory, must be <1>.
-
-The phandle's argument in the PHY specifier is the USB controller selector for
-the USB channel other than r8a77470 SoC; see the selector meanings below:
-
-+-----------+---------------+---------------+
-|\ Selector | | |
-+ --------- + 0 | 1 |
-| Channel \| | |
-+-----------+---------------+---------------+
-| 0 | PCI EHCI/OHCI | HS-USB |
-| 2 | PCI EHCI/OHCI | xHCI |
-+-----------+---------------+---------------+
-
-For r8a77470 SoC;see the selector meaning below:
-
-+-----------+---------------+---------------+
-|\ Selector | | |
-+ --------- + 0 | 1 |
-| Channel \| | |
-+-----------+---------------+---------------+
-| 0 | EHCI/OHCI | HS-USB |
-+-----------+---------------+---------------+
-
-Example (Lager board):
-
- usb-phy@e6590100 {
- compatible = "renesas,usb-phy-r8a7790", "renesas,rcar-gen2-usb-phy";
- reg = <0 0xe6590100 0 0x100>;
- #address-cells = <1>;
- #size-cells = <0>;
- clocks = <&cpg CPG_MOD 704>;
- clock-names = "usbhs";
- power-domains = <&sysc R8A7790_PD_ALWAYS_ON>;
- resets = <&cpg 704>;
-
- usb0: usb-channel@0 {
- reg = <0>;
- #phy-cells = <1>;
- };
- usb2: usb-channel@2 {
- reg = <2>;
- #phy-cells = <1>;
- };
- };
-
-Example (iWave RZ/G1C sbc):
-
- usbphy0: usb-phy0@e6590100 {
