   * @caps_offset:	offset of the EHCI Capability Registers to the start of
   *			the io memory region provided to the driver.
   * @has_tt:		set to 1 if TT is integrated in root hub.
   * @port_power_on:	set to 1 if the controller needs a power up after
   *			initialization.
   * @port_power_off:	set to 1 if the controller needs to be powered down
   *			after initialization.
   * @no_io_watchdog:	set to 1 if the controller does not need the I/O
   *			watchdog to run.
   * @reset_on_resume:	set to 1 if the controller needs to be reset after
   * 			a suspend / resume cycle (but can't detect that itself).
   *
   * These are general configuration options for the EHCI controller. All of
   * these options are activating more or less workarounds for some hardware.
