MODIFICATION HISTORY:

Ver   Who  Date     Changes



1.00a rmm  03/13/02 First release
2.00a jhl  11/26/03 Added support for dual channels and interrupts
2.01a jvb  12/14/05 I separated dependency on the static config table and
                    xparameters.h from the driver initialization by moving
                    _Initialize and _LookupConfig to _sinit.c. I also added
                    the new _CfgInitialize routine.
2.11a mta  03/21/07 Updated to new coding style, added GetDataDirection
2.12a sv   11/21/07 Updated driver to support access through DCR bus
2.12a sv   06/05/08 Updated driver to fix the XGpio_InterruptDisable function
              to properly update the Interrupt Enable register
2.13a sdm  08/22/08 Removed support for static interrupt handlers from the MDD
              file
3.00a sv   11/21/09 Updated to use HAL Processor APIs.
              Renamed the macros XGpio_mWriteReg to XGpio_WriteReg and
              XGpio_mReadReg to XGpio_ReadReg. Removed the macros
              XGpio_mSetDataDirection, XGpio_mGetDataReg and
              XGpio_mSetDataReg. Users should use XGpio_WriteReg and
              XGpio_ReadReg to achieve the same functionality.
3.01a bss  04/18/13 Updated driver tcl to generate Canonical params in
              xparameters.h. CR#698589
4.0   adk  19/12/13 Updated as per the New Tcl API's
4.1   lks  11/18/15 Updated to use canonical xparameters in examples and
              clean up of the comments, removed support for DCR bridge
              and removed xgpio_intr_example for CR 900381
4.2   sk   08/16/16 Used UINTPTR instead of u32 for Baseaddress as part of
                    adding 64 bit support. CR# 867425.
                    Changed the prototype of XGpio_CfgInitialize API.
4.3   sk   09/29/16 Modified the example to make it work when LED_bits are
                    configured as an output. CR# 958644
      ms   01/23/17 Added xil_printf statement in main function for all
                    examples to ensure that "Successfully ran" and "Failed"
                    strings are available in all examples. This is a fix
                    for CR-965028.
      ms   03/17/17 Added readme.txt file in examples folder for doxygen
                    generation.
4.4   sne  04/25/19 Updated Makefile for IAR compier (CR-1029421).
4.5   sne  06/14/19 Fixed IAR compiler warnings on example files.
4.6     sne  08/11/19 Fixed compilation error of armcc compiler.
4.7   sne  08/28/20 Modify Makefile to support parallel make execution.
4.8     sne  02/10/21 Fixed doxygen warnings.
4.10  gm   07/11/23 Added SDT support.
4.10  gm   08/28/23 Added Width member to XGpio_Config in SDT flow.
