* 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,iproc-nsp-sata-phy"
|
|
"brcm,phy-sata3"
|
|
"brcm,iproc-sr-sata-phy"
|
|
- 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" and "brcm,iproc-sr-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",
|
|
"brcm,iproc-nsp-sata-phy" and "brcm,iproc-sr-sata-phy".
|
|
|
|
- brcm,rxaeq-mode: string that indicates the desired RX equalizer
|
|
mode, possible values are:
|
|
"off" (equivalent to not specifying the property)
|
|
"auto"
|
|
"manual" (brcm,rxaeq-value is used in that case)
|
|
|
|
- brcm,rxaeq-value: when 'rxaeq-mode' is set to "manual", provides the RX
|
|
equalizer value that should be used. Allowed range is 0..63.
|
|
|
|
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>;
