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     "brcm,bcm63138-sata-phy"
12- address-cells: should be 1
13- size-cells: should be 0
14- reg: register ranges for the PHY PCB interface
15- reg-names: should be "phy" and "phy-ctrl"
16     The "phy-ctrl" registers are only required for
17     "brcm,iproc-ns2-sata-phy" and "brcm,iproc-sr-sata-phy".
18
19Sub-nodes:
20  Each port's PHY should be represented as a sub-node.
21
22Sub-nodes required properties:
23- reg: the PHY number
24- phy-cells: generic PHY binding; must be 0
25
26Sub-nodes optional properties:
27- brcm,enable-ssc: use spread spectrum clocking (SSC) on this port
28     This property is not applicable for "brcm,iproc-ns2-sata-phy",
29     "brcm,iproc-nsp-sata-phy" and "brcm,iproc-sr-sata-phy".
30
31- brcm,rxaeq-mode: string that indicates the desired RX equalizer
32  mode, possible values are:
33	"off" (equivalent to not specifying the property)
34	"auto"
35	"manual" (brcm,rxaeq-value is used in that case)
36
37- brcm,rxaeq-value: when 'rxaeq-mode' is set to "manual", provides the RX
38  equalizer value that should be used. Allowed range is 0..63.

41	sata-phy@f0458100 {
42		compatible = "brcm,bcm7445-sata-phy", "brcm,phy-sata3";
43		reg = <0xf0458100 0x1e00>, <0xf045804c 0x10>;
44		reg-names = "phy";
45		#address-cells = <1>;
46		#size-cells = <0>;
47
48		sata-phy@0 {
49			reg = <0>;
50			#phy-cells = <0>;
51		};
52
53		sata-phy@1 {
54			reg = <1>;
55			#phy-cells = <0>;
56		};
57	};
