| 2 | |
| 3 | Required 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 | |
| 9 | Optional 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 | |
| 35 | Required properties if child node exists: |
| 36 | |
| 37 | - #address-cells: Must be 1 |
| 38 | - #size-cells: Must be 1 |
| 39 | - ranges: must be present |
| 40 | |
| 41 | Properties for children: |
| 42 | |
| 43 | The OMAP HS USB Host subsystem contains EHCI and OHCI controllers. |
| 44 | See Documentation/devicetree/bindings/usb/omap-ehci.txt and |
| 45 | omap3-ohci.txt |
