-* Broadcom SATA3 AHCI Controller
-
-SATA nodes are defined to describe on-chip Serial ATA controllers.
-Each SATA controller should have its own node.
-
-Required properties:
-- compatible : should be one or more of
- "brcm,bcm7216-ahci"
- "brcm,bcm7425-ahci"
- "brcm,bcm7445-ahci"
- "brcm,bcm-nsp-ahci"
- "brcm,sata3-ahci"
- "brcm,bcm63138-ahci"
-- reg : register mappings for AHCI and SATA_TOP_CTRL
-- reg-names : "ahci" and "top-ctrl"
-- interrupts : interrupt mapping for SATA IRQ
-
-Optional properties:
-
-- reset: for "brcm,bcm7216-ahci" must be a valid reset phandle
- pointing to the RESCAL reset controller provider node.
-- reset-names: for "brcm,bcm7216-ahci", must be "rescal".
-
-Also see ahci-platform.txt.
-
-Example:
-
- sata@...5a000 {
- 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>;
- };
- };
