/**
*
* @file xccm.h
* 
* This header file contains identifiers and register-level driver functions (or
* macros), range macros, structure typedefs that can be used to access the
* Xilinx Color Correction Matrix (CCM) core instance.
*
* The Color Correction Matrix core offers a 3x3 matrix multiplication for a
* variety of color correction applications.
* CCM core provides following features:
*	- Fully programmable coefficient matrix.
*	- Offset compensation.
*	- Clipping and
*	- Clamping of the output.
*
* <b>Initialization & Configuration</b>
*
* The device driver enables higher layer software (e.g., an application) to
* communicate to the CCM core.
*
* XCcm_CfgInitialize() API is used to initialize the CCM core.
* The user needs to first call the XCcm_LookupConfig() API which returns
* the Configuration structure pointer which is passed as a parameter to the
* XCcm_CfgInitialize() API.
*
* <b> Interrupts </b>
*
* The driver provides an interrupt handler XCcm_IntrHandler for handling
* the interrupt from the CCM core. The users of this driver have to
* register this handler with the interrupt system and provide the callback
* functions by using XCcm_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 XCcm driver is composed of several source files. This allows the user
* to build and link only those parts of the driver that are necessary.
*
* <pre>
