* Broadcom SATA3 PHY for STB
Required properties:
- compatible: should be one or more of
"brcm,bcm7445-sata-phy"
"brcm,phy-sata3"
- address-cells: should be 1
- size-cells: should be 0
- reg: register range for the PHY PCB interface
- reg-names: should be "phy"
Sub-nodes:
Each port's PHY should be represented as a sub-node.
Sub-nodes required properties:
- reg: the PHY number
- phy-cells: generic PHY binding; must be 0
Optional:
- brcm,enable-ssc: use spread spectrum clocking (SSC) on this port
Example:
sata-phy@f0458100 {
compatible = "brcm,bcm7445-sata-phy", "brcm,phy-sata3";
reg = <0xf0458100 0x1e00>, <0xf045804c 0x10>;
reg-names = "phy";
#address-cells = <1>;
#size-cells = <0>;
sata-phy@0 {
reg = <0>;
#phy-cells = <0>;
};
sata-phy@1 {
reg = <1>;
#phy-cells = <0>;
};
};
