- 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";
- };
