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".

34 reg-names = "phy";
35 #address-cells = <1>;
36 #size-cells = <0>;
37
38 sata-phy@0 {
39 reg = <0>;
40 #phy-cells = <0>;
41 };
42
43 sata-phy@1 {
44 reg = <1>;
45 #phy-cells = <0>;
46 };
47 };
