-* 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, must contain "generic-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
-- assigned-clocks	: Shall be:
-				SATA_RXOOB_CLK
-				SATA_PMALIVE_CLK
-- assigned-clock-rates	: Shall be:
-				100Mhz (100000000) for SATA_RXOOB_CLK
-				100Mhz (100000000) for SATA_PMALIVE_CLK
-
-Example:
-	sata@29000000 {
-		compatible = "qcom,ipq806x-ahci", "generic-ahci";
-		reg = <0x29000000 0x180>;
