+AMCC SoC SATA Support
+
+This following is only for the 460ex support for Designware SATA core
+
+Required properties:
+- compatible : "amcc,sata-460ex".
+- reg : the first set defines SATA controller register, the second set
+ is for the AHB DMA controller for SATA.
+- interrupt-parent: UIC3
+- interrupts: one for SATA and one for the DMA
+
+Notes:
+The SATA is only available when the first PCIe port is disabled.
+
+Example:
+
+SATA0: sata@bffd1000 {
+ compatible = "amcc,sata-460ex";
+ reg = <4 0xbffd1000 0x800 4 0xbffd0800 0x400>;
+ interrupt-parent = <&UIC3>;
+ interrupts = <0 4 /* SATA */
+ 5 4>; /* AHBDMA */
+};
