-Broadcom STB USB PHY
-
-Required properties:
-- compatible: should be one of
- "brcm,brcmstb-usb-phy"
- "brcm,bcm7216-usb-phy"
- "brcm,bcm7211-usb-phy"
-
-- reg and reg-names properties requirements are specific to the
- compatible string.
- "brcm,brcmstb-usb-phy":
- - reg: 1 or 2 offset and length pairs. One for the base CTRL registers
- and an optional pair for systems with USB 3.x support
- - reg-names: not specified
- "brcm,bcm7216-usb-phy":
- - reg: 3 offset and length pairs for CTRL, XHCI_EC and XHCI_GBL
- registers
- - reg-names: "ctrl", "xhci_ec", "xhci_gbl"
- "brcm,bcm7211-usb-phy":
- - reg: 5 offset and length pairs for CTRL, XHCI_EC, XHCI_GBL,
- USB_PHY and USB_MDIO registers and an optional pair
- for the BDC registers
- - reg-names: "ctrl", "xhci_ec", "xhci_gbl", "usb_phy", "usb_mdio", "bdc_ec"
-
-- #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.
-- interrupts: wakeup interrupt
-- interrupt-names: "wakeup"
-- 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)
-- 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.
-- brcm,syscon-piarbctl: phandle to syscon for handling config registers
-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.
