  23 * struct usb_ehci_pdata - platform_data for generic ehci driver
  24 *
  25 * @caps_offset:        offset of the EHCI Capability Registers to the start of
  26 *                      the io memory region provided to the driver.
  27 * @has_tt:             set to 1 if TT is integrated in root hub.
  28 * @port_power_on:      set to 1 if the controller needs a power up after
  29 *                      initialization.
  30 * @port_power_off:     set to 1 if the controller needs to be powered down
  31 *                      after initialization.
  32 *
  33 * These are general configuration options for the EHCI controller. All of
  34 * these options are activating more or less workarounds for some hardware.
