  18 +Qualcomm IPQ806x SATA PHY Controller
  19 +------------------------------------
  20 +
  21 +SATA PHY nodes are defined to describe on-chip SATA Physical layer controllers.
  22 +Each SATA PHY controller should have its own node.
  23 +
  24 +Required properties:
  25 +- compatible: compatible list, contains "qcom,ipq806x-sata-phy"
  26 +- reg: offset and length of the SATA PHY register set;
  27 +- #phy-cells: must be zero
  28 +- clocks: must be exactly one entry
  29 +- clock-names: must be "cfg"
  30 +
  31 +Example:
  32 +       sata_phy: sata-phy@1b400000 {
  33 +               compatible = "qcom,ipq806x-sata-phy";
  34 +               reg = <0x1b400000 0x200>;
  35 +
  36 +               clocks = <&gcc SATA_PHY_CFG_CLK>;
  37 +               clock-names = "cfg";
  38 +
  39 +               #phy-cells = <0>;
  40 +       };
