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>,
|
|
<0xf0471940 0x6c0>;
|
|
compatible = "brcm,brcmstb-usb-phy";
|
|
#phy-cells = <1>;
|
|
dr_mode = "host"
|
|
brcm,ioc = <1>;
|
|
brcm,ipp = <1>;
|
|
brcm,has-xhci;
|
|
brcm,has-eohci;
|
|
clocks = <&usb20>, <&usb30>;
|
|
clock-names = "sw_usb", "sw_usb3";
|
|
};
