1Broadcom STB USB PHY
2
3Required properties:
4 - compatible: brcm,brcmstb-usb-phy
5 - reg: two offset and length pairs.
6	The first pair specifies a manditory set of memory mapped
7	registers used for general control of the PHY.
8	The second pair specifies optional registers used by some of
9	the SoCs that support USB 3.x
10 - #phy-cells: Shall be 1 as it expects one argument for setting
11	       the type of the PHY. Possible values are:
12	       - PHY_TYPE_USB2 for USB1.1/2.0 PHY
13	       - PHY_TYPE_USB3 for USB3.x PHY
14
15Optional Properties:
16- clocks : clock phandles.
17- clock-names: String, clock name.
18- brcm,ipp: Boolean, Invert Port Power.
19  Possible values are: 0 (Don't invert), 1 (Invert)
20- brcm,ioc: Boolean, Invert Over Current detection.
21  Possible values are: 0 (Don't invert), 1 (Invert)
22NOTE: one or both of the following two properties must be set
23- brcm,has-xhci: Boolean indicating the phy has an XHCI phy.
24- brcm,has-eohci: Boolean indicating the phy has an EHCI/OHCI phy.
25- dr_mode: String, PHY Device mode.
26  Possible values are: "host", "peripheral ", "drd" or "typec-pd"
27  If this property is not defined, the phy will default to "host" mode.
