|
|
||
|
|
Required properties:
|
||
|
|
- compatible: should be one or more of
|
||
|
|
"brcm,bcm7425-sata-phy"
|
||
|
|
"brcm,bcm7445-sata-phy"
|
||
|
|
"brcm,iproc-ns2-sata-phy"
|
||
|
|
"brcm,iproc-nsp-sata-phy"
|
||
|
|
"brcm,phy-sata3"
|
||
|
|
- address-cells: should be 1
|
||
|
|
- size-cells: should be 0
|
||
|
|
- 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.
|
||
|
|
|
||
|
|
Sub-nodes required properties:
|
||
|
|
- reg: the PHY number
|
||
|
|
- phy-cells: generic PHY binding; must be 0
|
||
|
|
|
||
|
|
Sub-nodes optional properties:
|
||
|
|
- brcm,enable-ssc: use spread spectrum clocking (SSC) on this port
|
||
|
|
This property is not applicable for "brcm,iproc-ns2-sata-phy" and
|
||
|
|
"brcm,iproc-nsp-sata-phy".
