OMAP HS USB Host Required properties: - compatible: should be "ti,usbhs-host" - reg: should contain one register range i.e. start and length - ti,hwmods: must contain "usb_host_hs" Optional properties: - num-ports: number of USB ports. Usually this is automatically detected from the IP's revision register but can be overridden by specifying this property. A maximum of 3 ports are supported at the moment. - portN-mode: String specifying the port mode for port N, where N can be from 1 to 3. If the port mode is not specified, that port is treated as unused. When specified, it must be one of the following. "ehci-phy", "ehci-tll", "ehci-hsic", "ohci-phy-6pin-datse0", "ohci-phy-6pin-dpdm", "ohci-phy-3pin-datse0", "ohci-phy-4pin-dpdm", "ohci-tll-6pin-datse0", "ohci-tll-6pin-dpdm", "ohci-tll-3pin-datse0", "ohci-tll-4pin-dpdm", "ohci-tll-2pin-datse0", "ohci-tll-2pin-dpdm", - single-ulpi-bypass: Must be present if the controller contains a single ULPI bypass control bit. e.g. OMAP3 silicon <= ES2.1 - clocks: a list of phandles and clock-specifier pairs, one for each entry in clock-names. - clock-names: should include: For OMAP3 * "usbhost_120m_fck" - 120MHz Functional clock. For OMAP4+ * "refclk_60m_int" - 60MHz internal reference clock for UTMI clock mux * "refclk_60m_ext_p1" - 60MHz external ref. clock for Port 1's UTMI clock mux. * "refclk_60m_ext_p2" - 60MHz external ref. clock for Port 2's UTMI clock mux * "utmi_p1_gfclk" - Port 1 UTMI clock mux. * "utmi_p2_gfclk" - Port 2 UTMI clock mux. * "usb_host_hs_utmi_p1_clk" - Port 1 UTMI clock gate. * "usb_host_hs_utmi_p2_clk" - Port 2 UTMI clock gate. * "usb_host_hs_utmi_p3_clk" - Port 3 UTMI clock gate. * "usb_host_hs_hsic480m_p1_clk" - Port 1 480MHz HSIC clock gate. * "usb_host_hs_hsic480m_p2_clk" - Port 2 480MHz HSIC clock gate. * "usb_host_hs_hsic480m_p3_clk" - Port 3 480MHz HSIC clock gate. * "usb_host_hs_hsic60m_p1_clk" - Port 1 60MHz HSIC clock gate. * "usb_host_hs_hsic60m_p2_clk" - Port 2 60MHz HSIC clock gate. * "usb_host_hs_hsic60m_p3_clk" - Port 3 60MHz HSIC clock gate. Required properties if child node exists: - #address-cells: Must be 1 - #size-cells: Must be 1 - ranges: must be present Properties for children: The OMAP HS USB Host subsystem contains EHCI and OHCI controllers. See Documentation/devicetree/bindings/usb/ehci-omap.txt and Documentation/devicetree/bindings/usb/ohci-omap3.txt. Example for OMAP4: usbhshost: usbhshost@4a064000 { compatible = "ti,usbhs-host"; reg = <0x4a064000 0x800>; ti,hwmods = "usb_host_hs"; #address-cells = <1>; #size-cells = <1>; ranges; usbhsohci: ohci@4a064800 { compatible = "ti,ohci-omap3", "usb-ohci"; reg = <0x4a064800 0x400>; interrupt-parent = <&gic>; interrupts = <0 76 0x4>; }; usbhsehci: ehci@4a064c00 { compatible = "ti,ehci-omap", "usb-ehci"; reg = <0x4a064c00 0x400>; interrupt-parent = <&gic>; interrupts = <0 77 0x4>; }; }; &usbhshost { port1-mode = "ehci-phy"; port2-mode = "ehci-tll"; port3-mode = "ehci-phy"; }; &usbhsehci { phys = <&hsusb1_phy 0 &hsusb3_phy>; };
