- * 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.

-/** @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_init function is called. When the module is
- * removed (using rmmod), the dwc_otg_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.

-/**
- * @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.

- **
- **                     The Host Controller Driver (HCD) is responsible for translating requests
- **                     from the USB Driver into the appropriate actions on the IFXUSB controller.
- **                     It isolates the USBD from the specifics of the controller by providing an
- **                     API to the USBD.

- \brief A URB Descriptor (URBD) holds the state of a bulk, control,
-  interrupt, or isochronous transfer. A single URBD is created for each URB
-  (of one of these types) submitted to the HCD. The transfer associated with
-  a URBD may require one or multiple transactions.
-
-  A URBD is linked to a EP Queue Head, which is entered in either the
-  isoc, intr or non-periodic schedule for execution. When a URBD is chosen for
-  execution, some or all of its transactions may be executed. After
-  execution, the state of the URBD is updated. The URBD may be retired if all
-  its transactions are complete or if an error occurred. Otherwise, it
-  remains in the schedule so more transactions can be executed later.

-   \brief This function does the setup for a data transfer for a host channel and
-  starts the transfer. May be called in either Slave mode or DMA mode. In
-  Slave mode, the caller must ensure that there is sufficient space in the
-  request queue and Tx Data FIFO.
-
-  For an OUT transfer in Slave mode, it loads a data packet into the
-  appropriate FIFO. If necessary, additional data packets will be loaded in
-  the Host ISR.
-
-  For an IN transfer in Slave mode, a data packet is requested. The data
-  packets are unloaded from the Rx FIFO in the Host ISR. If necessary,
-  additional data packets are requested in the Host ISR.
-
-  For a PING transfer in Slave mode, the Do Ping bit is set in the HCTSIZ
-  register along with a packet count of 1 and the channel is enabled. This
-  causes a single PING transaction to occur. Other fields in HCTSIZ are
-  simply set to 0 since no data transfer occurs in this case.
-
-  For a PING transfer in DMA mode, the HCTSIZ register is initialized with
-  all the information required to perform the subsequent data transfer. In
-  addition, the Do Ping bit is set in the HCTSIZ register. In this case, the
-  controller performs the entire PING protocol, then starts the data
-  transfer.
-
-  @param _ifxhc Information needed to initialize the host channel. The xfer_len
-  value may be reduced to accommodate the max widths of the XferSize and
-  PktCnt fields in the HCTSIZn register. The multi_count value may be changed
-  to reflect the final xfer_len value.

- **   DESCRIPTION     : The provides the initialization and cleanup entry
- **                     points for the IFX USB driver. This module can be
- **                     dynamically loaded with insmod command or built-in
- **                     with kernel. When loaded or executed the ifxusb_driver_init
- **                     function is called. When the module is removed (using rmmod),
- **                     the ifxusb_driver_cleanup function is called.

- **   DESCRIPTION     : This file contains the data structures for accessing the IFXUSB core
- **                     registers.
- **                     The application interfaces with the USB 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 USB 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.
