      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
     35- clocks: a list of phandles and clock-specifier pairs, one for each entry in
     36  clock-names.
     37
     38- clock-names: should include:
     39  For OMAP3
     40  * "usbhost_120m_fck" - 120MHz Functional clock.
     41
     42  For OMAP4+
     43  * "refclk_60m_int" - 60MHz internal reference clock for UTMI clock mux
     44  * "refclk_60m_ext_p1" - 60MHz external ref. clock for Port 1's UTMI clock mux.
     45  * "refclk_60m_ext_p2" - 60MHz external ref. clock for Port 2's UTMI clock mux
     46  * "utmi_p1_gfclk" - Port 1 UTMI clock mux.
     47  * "utmi_p2_gfclk" - Port 2 UTMI clock mux.
     48  * "usb_host_hs_utmi_p1_clk" - Port 1 UTMI clock gate.
     49  * "usb_host_hs_utmi_p2_clk" - Port 2 UTMI clock gate.
     50  * "usb_host_hs_utmi_p3_clk" - Port 3 UTMI clock gate.
     51  * "usb_host_hs_hsic480m_p1_clk" - Port 1 480MHz HSIC clock gate.
     52  * "usb_host_hs_hsic480m_p2_clk" - Port 2 480MHz HSIC clock gate.
     53  * "usb_host_hs_hsic480m_p3_clk" - Port 3 480MHz HSIC clock gate.
     54  * "usb_host_hs_hsic60m_p1_clk" - Port 1 60MHz HSIC clock gate.
     55  * "usb_host_hs_hsic60m_p2_clk" - Port 2 60MHz HSIC clock gate.
