Kernel-4.18.0-80.el8_brcm,brcmstb-usb-phy

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”;
};
