+* Calxeda AHCI SATA Controller
+
+SATA nodes are defined to describe on-chip Serial ATA controllers.
+The Calxeda SATA controller mostly conforms to the AHCI interface
+with some special extensions to add functionality.
+Each SATA controller should have its own node.
+
+Required properties:
+- compatible : compatible list, contains "calxeda,hb-ahci"
+- interrupts : <interrupt mapping for SATA IRQ>
+- reg : <registers mapping>
+
+Optional properties:
+- dma-coherent : Present if dma operations are coherent
+- calxeda,port-phys: phandle-combophy and lane assignment, which maps each
+ SATA port to a combophy and a lane within that
+ combophy
+- calxeda,sgpio-gpio: phandle-gpio bank, bit offset, and default on or off,
+ which indicates that the driver supports SGPIO
+ indicator lights using the indicated GPIOs
+- calxeda,led-order : a u32 array that map port numbers to offsets within the
+ SGPIO bitstream.
+
+Example:
+ sata@ffe08000 {
+ compatible = "calxeda,hb-ahci";
+ reg = <0xffe08000 0x1000>;
+ interrupts = <115>;
+ calxeda,port-phys = <&combophy5 0 &combophy0 0 &combophy0 1
