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.

FF
35 * @no_io_watchdog: set to 1 if the controller does not need the I/O
36 * watchdog to run.
314b41b1
WL
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).

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