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:
42
43The OMAP HS USB Host subsystem contains EHCI and OHCI controllers.
44See Documentation/devicetree/bindings/usb/omap-ehci.txt and
