   property. Required clocks are "xo", "iface_clk", "core_clk", "sleep_clk"

   and "utmi_clk".

  property.

Optional properties :

- reg: Additional registers

     initialize the internal MUX that controls whether to use USB3 controller

     with primary port.

     "ahb2phy_base" : top-level register to configure read/write wait cycle with

     both QMP and QUSB PHY registers.

  regulator node to the USB controller.

		TX fifo allocation in bytes

- qcom,usb-dbm : phandle for the DBM device

- qcom,lpm-to-suspend-delay-ms: Indicates timeout (in milliseconds) to release wakeup source

  after USB is kept into LPM.

- qcom,ext-hub-reset-gpio: This corresponds to gpio which is used for HUB reset.

- qcom,disable-dev-mode-pm: If present, it disables PM runtime functionality for device mode.

- qcom,disable-host-mode-pm: If present, it disables XHCI PM runtime functionality when USB

  host mode is used.

  hs speed.

- qcom,use-pdc-interrupts: It present, it configures provided PDC IRQ with required

  configuration for wakeup functionality.

- extcon: phandles to external connector devices. First phandle should point to

	  external connector, which provide type-C based "USB" cable events, the

	  second should point to external connector device, which provide type-C

	  "USB-HOST" cable events. A single phandle may be specified if a single

	  connector device provides both "USB" and "USB-HOST" events. An optional

	  third phandle may be specified for EUD based attach/detach events. A

	  mandatory fourth phandle has to be specified to provide microUSB based

	  "USB" cable events. An optional fifth phandle may be specified to provide

	  microUSB based "USB-HOST" cable events. Only the fourth phandle may be

	  specified if a single connector device provides both "USB" and "USB-HOST"

	  events.
