6 - compatible:	Should contain "qcom,ehci-host"
7 - regs:			offset and length of the register set in the memory map
8 - usb-phy:		phandle for the PHY device
13 		compatible = "qcom,ehci-host";
15 		usb-phy = <&usb_otg>;
18 USB PHY with optional OTG:
21 - compatible:   Should contain:
22   "qcom,usb-otg-ci" for chipsets with ChipIdea 45nm PHY
23   "qcom,usb-otg-snps" for chipsets with Synopsys 28nm PHY
25 - regs:         Offset and length of the register set in the memory map
26 - interrupts:   interrupt-specifier for the OTG interrupt.
28 - clocks:       A list of phandle + clock-specifier pairs for the
29                 clocks listed in clock-names
30 - clock-names:  Should contain the following:
31   "phy"         USB PHY reference clock
37 - vdccx-supply: phandle to the regulator for the vdd supply for
39 - v1p8-supply:  phandle to the regulator for the 1.8V supply
40 - v3p3-supply:  phandle to the regulator for the 3.3V supply
42 - resets:       A list of phandle + reset-specifier pairs for the
43                 resets listed in reset-names
44 - reset-names:  Should contain the following:
45   "phy"         USB PHY controller reset
46   "link"        USB LINK controller reset
48 - qcom,otg-control: OTG control (VBUS and ID notifications) can be one of
49                 1 - PHY control
50                 2 - PMIC control
53 - dr_mode:      One of "host", "peripheral" or "otg". Defaults to "otg"
55 - switch-gpio:  A phandle + gpio-specifier pair. Some boards are using Dual
56                 SPDT USB Switch, witch is controlled by GPIO to de/multiplex
57                 D+/D- USB lines between connectors.
59 - qcom,phy-init-sequence: PHY configuration sequence values. This is related to Device
61                 written is ULPI_EXT_VENDOR_SPECIFIC. Value of -1 is reserved as
63                 For example: qcom,phy-init-sequence = < -1 0x63 >;
66 - qcom,phy-num: Select number of pyco-phy to use, can be one of
67                 0 - PHY one, default
68                 1 - Second PHY
69                 Some platforms may have configuration to allow USB
72 - qcom,vdd-levels: This property must be a list of three integer values
73                 (no, min, max) where each value represents either a voltage
74                 in microvolts or a value corresponding to voltage corner.
76 - qcom,manual-pullup: If present, vbus is not routed to USB controller/phy
77                 and controller driver therefore enables pull-up explicitly
80 - extcon:       phandles to external connector devices. First phandle
81                 should point to external connector, which provide "USB"
82                 cable events, the second should point to external connector
83                 device, which provide "USB-HOST" cable events. If one of
84                 the external connector devices is not required empty <0>
