3 SATA nodes are defined to describe on-chip Serial ATA controllers.
4 Each SATA controller should have its own node.

6 Required properties:
7 - compatible         : should be one or more of
8                         "brcm,bcm7425-ahci"
9                         "brcm,bcm7445-ahci"
10                         "brcm,bcm-nsp-ahci"
11                         "brcm,sata3-ahci"
12 - reg                : register mappings for AHCI and SATA_TOP_CTRL
13 - reg-names          : "ahci" and "top-ctrl"
14 - interrupts         : interrupt mapping for SATA IRQ
