+* 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>;
+               };
+       };
