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 *
38 * These are general configuration options for the EHCI controller. All of
39 * these options are activating more or less workarounds for some hardware.
