+ * struct usb_ehci_pdata - platform_data for generic ehci driver
+ *
+ * @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.
