1* Broadcom SATA3 PHY
2
3Required properties:
4- compatible: should be one or more of
5     "brcm,bcm7425-sata-phy"
6     "brcm,bcm7445-sata-phy"
7     "brcm,iproc-ns2-sata-phy"
8     "brcm,iproc-nsp-sata-phy"
9     "brcm,phy-sata3"
10     "brcm,iproc-sr-sata-phy"
11- address-cells: should be 1
12- size-cells: should be 0
13- reg: register ranges for the PHY PCB interface
14- reg-names: should be "phy" and "phy-ctrl"
15     The "phy-ctrl" registers are only required for
16     "brcm,iproc-ns2-sata-phy" and "brcm,iproc-sr-sata-phy".
17
18Sub-nodes:
19  Each port's PHY should be represented as a sub-node.
20
21Sub-nodes required properties:
22- reg: the PHY number
23- phy-cells: generic PHY binding; must be 0
24
25Sub-nodes optional properties:
26- brcm,enable-ssc: use spread spectrum clocking (SSC) on this port
27     This property is not applicable for "brcm,iproc-ns2-sata-phy",
28     "brcm,iproc-nsp-sata-phy" and "brcm,iproc-sr-sata-phy".
29
30- brcm,rxaeq-mode: string that indicates the desired RX equalizer
31  mode, possible values are:
32	"off" (equivalent to not specifying the property)
33	"auto"
34	"manual" (brcm,rxaeq-value is used in that case)
35
36- brcm,rxaeq-value: when 'rxaeq-mode' is set to "manual", provides the RX
37  equalizer value that should be used. Allowed range is 0..63.

52		sata-phy@1 {
53			reg = <1>;
54			#phy-cells = <0>;
55		};
