* Broadcom SATA3 PHY for STB
* Broadcom SATA3 PHY
Required properties:
- compatible: should be one or more of
"brcm,bcm7425-sata-phy"
"brcm,bcm7445-sata-phy"
"brcm,iproc-ns2-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"
- reg: register ranges for the PHY PCB interface
- reg-names: should be "phy" and "phy-ctrl"
The "phy-ctrl" registers are only required for
"brcm,iproc-ns2-sata-phy".
Sub-nodes:
Each port's PHY should be represented as a sub-node.
