/**
 * 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.
