   1 * Broadcom SATA3 PHY
   2
   3 Required properties:
   4 - compatible: should be one or more of
   5      "brcm,bcm7425-sata-phy"
   6      "brcm,bcm7445-sata-phy"
   7      "brcm,iproc-ns2-sata-phy"
   8      "brcm,iproc-nsp-sata-phy"
   9      "brcm,phy-sata3"
  10 - address-cells: should be 1
  11 - size-cells: should be 0
  12 - reg: register ranges for the PHY PCB interface
  13 - reg-names: should be "phy" and "phy-ctrl"
  14      The "phy-ctrl" registers are only required for
  15      "brcm,iproc-ns2-sata-phy".
  16
  17 Sub-nodes:
  18   Each port's PHY should be represented as a sub-node.
  19
  20 Sub-nodes required properties:
  21 - reg: the PHY number
  22 - phy-cells: generic PHY binding; must be 0
  23
  24 Sub-nodes optional properties:
  25 - brcm,enable-ssc: use spread spectrum clocking (SSC) on this port
  26      This property is not applicable for "brcm,iproc-ns2-sata-phy" and
  27      "brcm,iproc-nsp-sata-phy".
