Detailed Description

struct usb_ehci_pdata - platform_data for generic ehci driver

: offset of the EHCI Capability Registers to the start of the io memory region provided to the driver. : set to 1 if TT is integrated in root hub. : set to 1 if the controller needs a power up after initialization. : set to 1 if the controller needs to be powered down after initialization.

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