-+ * Gadget Zero only needs two bulk endpoints, and is an example of how you

-+ *
-+ * 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).

-+ * 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.

-+ * 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

-+ * 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

-+ *
-+ * 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.
