  18 +* Qualcomm AHCI SATA Controller
  19 +
  20 +SATA nodes are defined to describe on-chip Serial ATA controllers.
  21 +Each SATA controller should have its own node.
  22 +
  23 +Required properties:
  24 +- compatible           : compatible list, contains "qcom,msm-ahci"
  25 +- interrupts           : <interrupt mapping for SATA IRQ>
  26 +- reg                  : <registers mapping>
  27 +- phys                 : Must contain exactly one entry as specified
  28 +                         in phy-bindings.txt
  29 +- phy-names            : Must be "sata-phy"
  30 +
  31 +Required properties for "qcom,ipq806x-ahci" compatible:
  32 +- clocks               : Must contain an entry for each entry in clock-names.
  33 +- clock-names          : Shall be:
  34 +                               "slave_iface" - Fabric port AHB clock for SATA
  35 +                               "iface" - AHB clock
  36 +                               "core" - core clock
  37 +                               "rxoob" - RX out-of-band clock
  38 +                               "pmalive" - Power Module Alive clock
  39 +
  40 +Example:
  41 +       sata@29000000 {
  42 +               compatible = "qcom,ipq806x-ahci", "qcom,msm-ahci";
  43 +               reg = <0x29000000 0x180>;
  44 +
  45 +               interrupts = <0 209 0x0>;
  46 +
