For Axon: 0x0000012a
+ 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:
+
+ [EMAIL PROTECTED] {
+ 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.
