  * @brief   DMA2D HAL module driver.
  *          This file provides firmware functions to manage the following 
  *          functionalities of the DMA2D peripheral:
  *           + Initialization and de-initialization functions
  *           + IO operation functions
  *           + Peripheral Control functions 
  *           + Peripheral State and Errors functions

  @verbatim 
  ==============================================================================
                        ##### How to use this driver #####
  ==============================================================================
    [..]
      (#) Program the required configuration through following parameters:   
          the Transfer Mode, the output color mode and the output offset using 
          HAL_DMA2D_Init() function.

      (#) Program the required configuration through following parameters:   
          the input color mode, the input color, input alpha value, alpha mode 
          and the input offset using HAL_DMA2D_ConfigLayer() function for foreground
          or/and background layer.
          
     *** Polling mode IO operation ***
     =================================   
    [..]        
       (+) Configure the pdata, Destination and data length and Enable 
           the transfer using HAL_DMA2D_Start() 
       (+) Wait for end of transfer using HAL_DMA2D_PollForTransfer(), at this stage
           user can specify the value of timeout according to his end application.
               
     *** Interrupt mode IO operation ***    
     ===================================
     [..] 
       (#) Configure the pdata, Destination and data length and Enable 
           the transfer using HAL_DMA2D_Start_IT() 
       (#) Use HAL_DMA2D_IRQHandler() called under DMA2D_IRQHandler() Interrupt subroutine
       (#) At the end of data transfer HAL_DMA2D_IRQHandler() function is executed and user can 
           add his own function by customization of function pointer XferCpltCallback and 
           XferErrorCallback (i.e a member of DMA2D handle structure). 

         -@-   In Register-to-Memory transfer mode, the pdata parameter is the register
               color, in Memory-to-memory or memory-to-memory with pixel format
               conversion the pdata is the source address.

         -@-   Configure the foreground source address, the background source address, 
               the Destination and data length and Enable the transfer using 
               HAL_DMA2D_BlendingStart() in polling mode and HAL_DMA2D_BlendingStart_IT()
               in interrupt mode.
               
         -@-   HAL_DMA2D_BlendingStart() and HAL_DMA2D_BlendingStart_IT() functions
               are used if the memory to memory with blending transfer mode is selected.
                   
      (#) Optionally, configure and enable the CLUT using HAL_DMA2D_ConfigCLUT()
          HAL_DMA2D_EnableCLUT() functions.

      (#) Optionally, configure and enable LineInterrupt using the following function:
          HAL_DMA2D_ProgramLineEvent().
   
      (#) The transfer can be suspended, continued and aborted using the following
          functions: HAL_DMA2D_Suspend(), HAL_DMA2D_Resume(), HAL_DMA2D_Abort().
                     
      (#) To control DMA2D state you can use the following function: HAL_DMA2D_GetState()                   

     *** DMA2D HAL driver macros list ***
     ============================================= 
     [..]
       Below the list of most used macros in DMA2D HAL driver :
       
      (+) __HAL_DMA2D_ENABLE: Enable the DMA2D peripheral.
      (+) __HAL_DMA2D_DISABLE: Disable the DMA2D peripheral.
      (+) __HAL_DMA2D_GET_FLAG: Get the DMA2D pending flags.
      (+) __HAL_DMA2D_CLEAR_FLAG: Clear the DMA2D pending flags.
      (+) __HAL_DMA2D_ENABLE_IT: Enable the specified DMA2D interrupts.
