3Required properties:
4- compatible: should be one of
5	"brcm,brcmstb-usb-phy"
6	"brcm,bcm7216-usb-phy"
7	"brcm,bcm7211-usb-phy"
8
9- reg and reg-names properties requirements are specific to the
10  compatible string.
11  "brcm,brcmstb-usb-phy":
12    - reg: 1 or 2 offset and length pairs. One for the base CTRL registers
13           and an optional pair for systems with USB 3.x support
14    - reg-names: not specified
15  "brcm,bcm7216-usb-phy":
16    - reg: 3 offset and length pairs for CTRL, XHCI_EC and XHCI_GBL
17           registers
18    - reg-names: "ctrl", "xhci_ec", "xhci_gbl"
19  "brcm,bcm7211-usb-phy":
20    - reg: 5 offset and length pairs for CTRL, XHCI_EC, XHCI_GBL,
21           USB_PHY and USB_MDIO registers and an optional pair
22	   for the BDC registers
23    - reg-names: "ctrl", "xhci_ec", "xhci_gbl", "usb_phy", "usb_mdio", "bdc_ec"
24
25- #phy-cells: Shall be 1 as it expects one argument for setting
26	      the type of the PHY. Possible values are:
27	      - PHY_TYPE_USB2 for USB1.1/2.0 PHY
28	      - PHY_TYPE_USB3 for USB3.x PHY
29
30Optional Properties:
31- clocks : clock phandles.
32- clock-names: String, clock name.
33- interrupts: wakeup interrupt
34- interrupt-names: "wakeup"
35- brcm,ipp: Boolean, Invert Port Power.
36  Possible values are: 0 (Don't invert), 1 (Invert)
37- brcm,ioc: Boolean, Invert Over Current detection.
38  Possible values are: 0 (Don't invert), 1 (Invert)
39- dr_mode: String, PHY Device mode.
40  Possible values are: "host", "peripheral ", "drd" or "typec-pd"
41  If this property is not defined, the phy will default to "host" mode.
42- brcm,syscon-piarbctl: phandle to syscon for handling config registers
43NOTE: one or both of the following two properties must be set
44- brcm,has-xhci: Boolean indicating the phy has an XHCI phy.
45- brcm,has-eohci: Boolean indicating the phy has an EHCI/OHCI phy.
