-+ * The Core Interface Layer provides basic services for accessing and

-+ * 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

-+/** @file
-+ * 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.

-+ * This file implements the Peripheral Controller Driver.
-+ *
-+ * The Peripheral Controller Driver (PCD) is responsible for
-+ * translating requests from the Function Driver into the appropriate
-+ * actions on the DWC_otg controller. It isolates the Function Driver
-+ * 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

-+ * @file
-+ *
-+ * This file contains the data structures for accessing the DWC_otg core registers.
-+ *
-+ * The application interfaces with the HS OTG core by reading from and
-+ * writing to the Control and Status Register (CSR) space through the
-+ * AHB Slave interface. These registers are 32 bits wide, and the
-+ * addresses are 32-bit-block aligned.
-+ * CSRs are classified as follows:
-+ * - Core Global Registers
-+ * - Device Mode Registers
-+ * - Device Global Registers
-+ * - Device Endpoint Specific Registers
-+ * - Host Mode Registers
-+ * - Host Global Registers
-+ * - Host Port CSRs
-+ * - Host Channel Specific Registers
-+ *
-+ * Only the Core Global registers can be accessed in both Device and
-+ * Host modes. When the HS OTG core is operating in one mode, either
-+ * Device or Host, the application must not access registers from the
-+ * other mode. When the core switches from one mode to another, the
-+ * registers in the new mode of operation must be reprogrammed as they
-+ * would be after a power-on reset.
