   4 This comphy controller can be found on Marvell Armada 38x. It provides a
   5 number of shared PHYs used by various interfaces (network, sata, usb,
   6 PCIe...).
   7
   8 Required properties:
   9
  10 - compatible: should be "marvell,armada-380-comphy"
  11 - reg: should contain the comphy register location and length.
  12 - #address-cells: should be 1.
  13 - #size-cells: should be 0.
  14
  15 Optional properties:
  16
  17 - reg-names: must be "comphy" as the first name, and "conf".
  18 - reg: must contain the comphy register location and length as the first
  19     pair, followed by an optional configuration register address and
  20     length pair.
  21
  22 A sub-node is required for each comphy lane provided by the comphy.
  23
  24 Required properties (child nodes):
  25
  26 - reg: comphy lane number.
  27 - #phy-cells : from the generic phy bindings, must be 1. Defines the
  28                input port to use for a given comphy lane.

  30 Example:
  31
  32         comphy: phy@18300 {
  33                 compatible = "marvell,armada-380-comphy";
  34                 reg-names = "comphy", "conf";
  35                 reg = <0x18300 0x100>, <0x18460 4>;
  36                 #address-cells = <1>;
  37                 #size-cells = <0>;
  38
  39                 cpm_comphy0: phy@0 {
  40                         reg = <0>;
  41                         #phy-cells = <1>;
  42                 };
  43
  44                 cpm_comphy1: phy@1 {
  45                         reg = <1>;
  46                         #phy-cells = <1>;
  47                 };
  48         };
