+    o) SATA nodes
+
+    SATA nodes are defined to describe on-chip Serial ATA controllers.
+
+    Required properties:
+
+    - compatible : Should specify what this SATA controller is compatible
+      with.
+    - reg : Offset and length of the register set for the device.
+    - interrupts : <a b> where a is the interrupt number and b is a
+      field that represents an encoding of the sense and level
+      information for the interrupt.  This should be encoded based on
+      the information in section 2) depending on the type of interrupt
+      controller you have.
+    - interrupt-parent : the phandle for the interrupt controller that
+      services interrupts for this device.
+
+    Recommended properties :
+
+    - phy-handle : Some SATA controller uses a shared SerDes PHY. This
+      property should specify the phandle of the SerDes node.
+
+   Example:
+
+	sata@19000 {
+		compatible = "fsl,mpc8315-sata";
+		reg = <19000 1000>;
+		interrupts = <2d 8>;
+		interrupt-parent = < &ipic >;
+		phy-handle = < &serdes1 >;
+        };
+
    More devices will be defined as this spec matures.
