35 * The dwc_otg_driver module provides the initialization and cleanup entry
36 * points for the DWC_otg driver. This module will be dynamically installed
37 * after Linux is booted using the insmod command. When the module is
38 * installed, the dwc_otg_driver_init function is called. When the module is
39 * removed (using rmmod), the dwc_otg_driver_cleanup function is called.
41 * This module also defines a data structure for the dwc_otg_driver, which is
42 * used in conjunction with the standard ARM lm_device structure. These
43 * structures allow the OTG driver to comply with the standard Linux driver
44 * model in which devices and drivers are registered with a bus driver. This
45 * has the benefit that Linux can expose attributes of the driver and device
46 * in its special sysfs file system. Users can then read or write files in
47 * this file system to perform diagnostics on the driver components or the
