-* APM X-Gene 6.0 Gb/s SATA host controller nodes
-
-SATA host controller nodes are defined to describe on-chip Serial ATA
-controllers. Each SATA controller (pair of ports) have its own node.
-
-Required properties:
-- compatible		: Shall contain:
-  * "apm,xgene-ahci"
-- reg			: First memory resource shall be the AHCI memory
-			  resource.
-			  Second memory resource shall be the host controller
-			  core memory resource.
-			  Third memory resource shall be the host controller
-			  diagnostic memory resource.
-			  4th memory resource shall be the host controller
-			  AXI memory resource.
-			  5th optional memory resource shall be the host
-			  controller MUX memory resource if required.
-- interrupts		: Interrupt-specifier for SATA host controller IRQ.
-- clocks		: Reference to the clock entry.
-- phys			: A list of phandles + phy-specifiers, one for each
-			  entry in phy-names.
-- phy-names		: Should contain:
-  * "sata-phy" for the SATA 6.0Gbps PHY
-
-Optional properties:
-- dma-coherent		: Present if dma operations are coherent
-- status		: Shall be "ok" if enabled or "disabled" if disabled.
-			  Default is "ok".
-
-Example:
-		sataclk: sataclk {
-			compatible = "fixed-clock";
-			#clock-cells = <1>;
-			clock-frequency = <100000000>;
-			clock-output-names = "sataclk";

-			compatible = "apm,xgene-phy";
-			reg = <0x0 0x1f23a000 0x0 0x100>;
