+ * @file xqspipsu_control.h
+ * @addtogroup Overview
+ * @{
+ *
+ * This is the header file for the implementation of QSPIPSU driver.
+ * Generic QSPI interface allows for communication to any QSPI slave device.
+ * GQSPI contains a GENFIFO into which the bus transfers required are to be
+ * pushed with appropriate configuration. The controller provides TX and RX
+ * FIFO's and a DMA to be used for RX transfers. The controller executes each
+ * GENFIFO entry noting the configuration and places data on the bus as required
+ *
+ *
+ * <pre>
+ * MODIFICATION HISTORY:
+ *
+ * Ver   Who Date     Changes
+ * ----- --- -------- -----------------------------------------------.
+ * 1.11   akm  03/09/20 First release
+ * 1.13   akm  01/04/21 Fix MISRA-C violations.
+ * 1.15   akm  03/03/22 Enable tapdelay settings for applications on
+ * 			 Microblaze platform.
