1OMAP HS USB Host
2
3Required properties:
4
5- compatible: should be "ti,usbhs-host"
6- reg: should contain one register range i.e. start and length
7- ti,hwmods: must contain "usb_host_hs"
8
9Optional properties:
10
11- num-ports: number of USB ports. Usually this is automatically detected
12  from the IP's revision register but can be overridden by specifying
13  this property. A maximum of 3 ports are supported at the moment.
14
15- portN-mode: String specifying the port mode for port N, where N can be
16  from 1 to 3. If the port mode is not specified, that port is treated
17  as unused. When specified, it must be one of the following.
18	"ehci-phy",
19        "ehci-tll",
20        "ehci-hsic",
21        "ohci-phy-6pin-datse0",
22        "ohci-phy-6pin-dpdm",
23        "ohci-phy-3pin-datse0",
24        "ohci-phy-4pin-dpdm",
25        "ohci-tll-6pin-datse0",
26        "ohci-tll-6pin-dpdm",
27        "ohci-tll-3pin-datse0",
28        "ohci-tll-4pin-dpdm",
29        "ohci-tll-2pin-datse0",
30        "ohci-tll-2pin-dpdm",
31
32- single-ulpi-bypass: Must be present if the controller contains a single
33  ULPI bypass control bit. e.g. OMAP3 silicon <= ES2.1
34
35Required properties if child node exists:
36
37- #address-cells: Must be 1
38- #size-cells: Must be 1
39- ranges: must be present
40
41Properties for children:
