++* Qualcomm AHCI SATA Controller
++
++SATA nodes are defined to describe on-chip Serial ATA controllers.
++Each SATA controller should have its own node.
++
++Required properties:
++- compatible          : compatible list, contains "qcom,msm-ahci"
++- interrupts          : <interrupt mapping for SATA IRQ>
++- reg                 : <registers mapping>
++- phys                        : Must contain exactly one entry as specified
++                        in phy-bindings.txt
++- phy-names           : Must be "sata-phy"
++
++Required properties for "qcom,ipq806x-ahci" compatible:
++- clocks              : Must contain an entry for each entry in clock-names.
++- clock-names         : Shall be:
++                              "slave_iface" - Fabric port AHB clock for SATA
++                              "iface" - AHB clock
++                              "core" - core clock
++                              "rxoob" - RX out-of-band clock
++                              "pmalive" - Power Module Alive clock
++
++Example:
++      sata@29000000 {
++              compatible = "qcom,ipq806x-ahci", "qcom,msm-ahci";
++              reg = <0x29000000 0x180>;
++
++              interrupts = <0 209 0x0>;
++
++              clocks = <&gcc SFAB_SATA_S_H_CLK>,
++                       <&gcc SATA_H_CLK>,
++                       <&gcc SATA_A_CLK>,
++                       <&gcc SATA_RXOOB_CLK>,
++                       <&gcc SATA_PMALIVE_CLK>;
++              clock-names = "slave_iface", "iface", "core",
++                              "rxoob", "pmalive";
++
++              phys = <&sata_phy>;
++              phy-names = "sata-phy";
++      };
