+* Broadcom SATA3 AHCI Controller for STB
+
+SATA nodes are defined to describe on-chip Serial ATA controllers.
+Each SATA controller should have its own node.
+
+Required properties:
+- compatible : compatible list, may contain "brcm,bcm7445-ahci" and/or
+ "brcm,sata3-ahci"
+- reg : register mappings for AHCI and SATA_TOP_CTRL
+- reg-names : "ahci" and "top-ctrl"
+- interrupts : interrupt mapping for SATA IRQ
+
+Also see ahci-platform.txt.
+
+Example:
+
+ sata@f045a000 {
+ compatible = "brcm,bcm7445-ahci", "brcm,sata3-ahci";
+ reg = <0xf045a000 0xa9c>, <0xf0458040 0x24>;
+ reg-names = "ahci", "top-ctrl";
+ interrupts = <0 30 0>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ sata0: sata-port@0 {
+ reg = <0>;
+ phys = <&sata_phy 0>;
+ };
+
+ sata1: sata-port@1 {
+ reg = <1>;
+ phys = <&sata_phy 1>;
+ };
+ };
