++ * Gadget Zero only needs two bulk endpoints, and is an example of how you
++ * can write a hardware-agnostic gadget driver running inside a USB device.
++ *
++ * Hardware details are visible (see CONFIG_USB_ZERO_* below) but don't
++ * affect most of the driver.
++ *
++ * Use it with the Linux host/master side "usbtest" driver to get a basic
++ * functional test of your device-side usb stack, or with "usb-skeleton".
++ *
++ * It supports two similar configurations. One sinks whatever the usb host
++ * writes, and in return sources zeroes. The other loops whatever the host
++ * writes back, so the host can read it. Module options include:
++ *
++ * buflen=N default N=4096, buffer size used
++ * qlen=N default N=32, how many buffers in the loopback queue
++ * loopdefault default false, list loopback config first
++ *
++ * Many drivers will only have one configuration, letting them be much
++ * simpler if they also don't support high speed operation (like this
++ * driver does).

++ *
++ * The Core Interface Layer provides basic services for accessing and
++ * managing the DWC_otg hardware. These services are used by both the
++ * Host Controller Driver and the Peripheral Controller Driver.
++ *
++ * The CIL manages the memory map for the core so that the HCD and PCD
++ * don't have to do this separately. It also handles basic tasks like
++ * reading/writing the registers and data FIFOs in the controller.
++ * Some of the data access functions provide encapsulation of several
++ * operations required to perform a task, such as writing multiple
++ * registers to start a transfer. Finally, the CIL performs basic
++ * services that are not specific to either the host or device modes
++ * of operation. These services include management of the OTG Host
++ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A
++ * Diagnostic API is also provided to allow testing of the controller
++ * hardware.
++ *
++ * The Core Interface Layer has the following requirements:
++ * - Provides basic controller operations.
++ * - Minimal use of OS services.
++ * - The OS services used will be abstracted by using inline functions
++ * or macros.

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

++ * from the specifics of the controller by providing an API to the
++ * Function Driver.
++ *
++ * The Peripheral Controller Driver for Linux will implement the
++ * Gadget API, so that the existing Gadget drivers can be used.
++ * (Gadget Driver is the Linux terminology for a Function Driver.)
++ *
++ * The Linux Gadget API is defined in the header file
++ * <code><linux/usb_gadget.h></code>. The USB EP operations API is
++ * defined in the structure <code>usb_ep_ops</code> and the USB
++ * Controller API is defined in the structure
++ * <code>usb_gadget_ops</code>.
++ *
++ * An important function of the PCD is managing interrupts generated
++ * by the DWC_otg controller. The implementation of the DWC_otg device
++ * mode interrupt service routines is in dwc_otg_pcd_intr.c.
++ *
++ * @todo Add Device Mode test modes (Test J mode, Test K mode, etc).
++ * @todo Does it work when the request size is greater than DEPTSIZ
++ * transfer size
