    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
   28 
   29 Example:
   30         sata@29000000 {
   31                 compatible = "qcom,ipq806x-ahci", "generic-ahci";
   32                 reg = <0x29000000 0x180>;
   33 
   34                 interrupts = <0 209 0x0>;

   42                                 "rxoob", "pmalive";
   43                 assigned-clocks = <&gcc SATA_RXOOB_CLK>, <&gcc SATA_PMALIVE_CLK>;
   44                 assigned-clock-rates = <100000000>, <100000000>;
