   1 * Qualcomm AHCI SATA Controller
   2
   3 SATA nodes are defined to describe on-chip Serial ATA controllers.
   4 Each SATA controller should have its own node.
   5
   6 Required properties:
   7 - compatible            : compatible list, must contain "generic-ahci"
   8 - interrupts            : <interrupt mapping for SATA IRQ>
   9 - reg                   : <registers mapping>
  10 - phys                  : Must contain exactly one entry as specified
  11                           in phy-bindings.txt
  12 - phy-names             : Must be "sata-phy"
  13
  14 Required properties for "qcom,ipq806x-ahci" compatible:
  15 - clocks                : Must contain an entry for each entry in clock-names.
  16 - clock-names           : Shall be:
  17                                 "slave_iface" - Fabric port AHB clock for SATA
  18                                 "iface" - AHB clock
  19                                 "core" - core clock
  20                                 "rxoob" - RX out-of-band clock
  21                                 "pmalive" - Power Module Alive clock
  22 - assigned-clocks       : Shall be:
  23                                 SATA_RXOOB_CLK
  24                                 SATA_PMALIVE_CLK
  25 - assigned-clock-rates  : Shall be:
  26                                 100Mhz (100000000) for SATA_RXOOB_CLK
  27                                 100Mhz (100000000) for SATA_PMALIVE_CLK
