Broadcom STB USB PHY
|
||||
|
||||
Required properties:
|
||||
- compatible: brcm,brcmstb-usb-phy
|
||||
- reg: two offset and length pairs.
|
||||
The first pair specifies a manditory set of memory mapped
|
||||
registers used for general control of the PHY.
|
||||
The second pair specifies optional registers used by some of
|
||||
the SoCs that support USB 3.x
|
||||
- #phy-cells: Shall be 1 as it expects one argument for setting
|
||||
the type of the PHY. Possible values are:
|
||||
- PHY_TYPE_USB2 for USB1.1/2.0 PHY
|
||||
- PHY_TYPE_USB3 for USB3.x PHY
|
||||
|
||||
Optional Properties:
|
||||
- clocks : clock phandles.
|
||||
- clock-names: String, clock name.
|
||||
- brcm,ipp: Boolean, Invert Port Power.
|
||||
Possible values are: 0 (Don't invert), 1 (Invert)
|
||||
- brcm,ioc: Boolean, Invert Over Current detection.
|
||||
Possible values are: 0 (Don't invert), 1 (Invert)
|
||||
NOTE: one or both of the following two properties must be set
|
||||
- brcm,has-xhci: Boolean indicating the phy has an XHCI phy.
|
||||
- brcm,has-eohci: Boolean indicating the phy has an EHCI/OHCI phy.
|
||||
- dr_mode: String, PHY Device mode.
|
||||
Possible values are: "host", "peripheral ", "drd" or "typec-pd"
|
||||
If this property is not defined, the phy will default to "host" mode.
|
||||
|
||||
Example:
|
||||
|
||||
usbphy_0: usb-phy@f0470200 {
|
||||
reg = <0xf0470200 0xb8>,
|

|

||||
clock-names = "sw_usb", "sw_usb3";

||||
};

||||
This property is not applicable for "brcm,iproc-ns2-sata-phy",
|
||||
"brcm,iproc-nsp-sata-phy" and "brcm,iproc-sr-sata-phy".
|
||||
|
||||
Example:
|
||||
- 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.
