/**
*
* @file xtpg.h
*
* This header file contains identifiers and register-level driver functions (or
* macros) that can be used to access the Xilinx Test Pattern Generator
* (TPG) core instance.
*
* The TPG core provides a wide variety of tests patterns enabling you to debug
* and assess video system color, quality, edge, and motion performance.
*
* The Test Pattern Generator core produces the following patterns in RGB,
* YCbCr 444, or YCbCr 422 video format.
*	- Video input pass through
*	- Horizontal ramp
*	- Vertical ramp
*	- Temporal ramp
*	- Flat fields (red, green, blue, black and white)
*	- Combined vertical and horizontal ramp
*	- Color bars
*	- Tartan bars
*	- Zone plate
*	- Cross hairs
*	- Cross hatch
*	- Solid box
*	- Motion effect for ramps, zone plate, and solid box
*
* <b>Initialization & Configuration</b>
*
* The device driver enables higher layer software (e.g., an application) to
* communicate to the TPG core.
*
* XTpg_CfgInitialize() API is used to initialize the TPG core.
* The user needs to first call the XTpg_LookupConfig() API which returns
* the Configuration structure pointer which is passed as a parameter to the
* XTpg_CfgInitialize() API.
*
* <b> Interrupts </b>
*
* The driver provides an interrupt handler XTpg_IntrHandler for handling
* the interrupt from the TPG core. The users of this driver have to
* register this handler with the interrupt system and provide the callback
* functions by using XTpg_SetCallBack API.
*
* <b> Virtual Memory </b>
*
* This driver supports Virtual Memory. The RTOS is responsible for calculating
* the correct device base address in Virtual Memory space.
*
* <b> Threads </b>
*
* This driver is not thread safe. Any needs for threads or thread mutual
* exclusion must be satisfied by the layer above this driver.
*
* <b> Asserts </b>
*
* Asserts are used within all Xilinx drivers to enforce constraints on argument
* values. Asserts can be turned off on a system-wide basis by defining, at
* compile time, the NDEBUG identifier. By default, asserts are turned on and it
* is recommended that users leave asserts on during development.
*
* <b> Building the driver </b>
*
* The XTpg driver is composed of several source files. This allows the user
* to build and link only those parts of the driver that are necessary.
*
