+/**
+ * @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.
