  26 * struct usb_ehci_pdata - platform_data for generic ehci driver
  27 *
  28 * @caps_offset:        offset of the EHCI Capability Registers to the start of
  29 *                      the io memory region provided to the driver.
  30 * @has_tt:             set to 1 if TT is integrated in root hub.
  31 * @port_power_on:      set to 1 if the controller needs a power up after
  32 *                      initialization.
  33 * @port_power_off:     set to 1 if the controller needs to be powered down
  34 *                      after initialization.
  35 * @no_io_watchdog:     set to 1 if the controller does not need the I/O
  36 *                      watchdog to run.
  37 * @reset_on_resume:    set to 1 if the controller needs to be reset after
  38 *                      a suspend / resume cycle (but can't detect that itself).
  39 *
  40 * These are general configuration options for the EHCI controller. All of
  41 * these options are activating more or less workarounds for some hardware.
