    MODIFICATION HISTORY:

    Ver   Who    Date     Changes

    1.00         10/07/15 Initial release.
    1.01  MG     17/12/16 Fixed issue in function SetAudioChannels
                          Updated function XV_HdmiTxSs_SendAuxInfoframe
    1.02  yh     12/01/16 Check vtc existance before configuring it
    1.03  yh     15/01/16 Add 3D Support
    1.04  yh     20/01/16 Added remapper support
    1.05  yh     01/02/16 Added set_ppc api
    1.06  yh     01/02/16 Removed xil_print "Cable (dis)connected"
    1.07  yh     15/02/16 Added default value to XV_HdmiTxSs_ConfigRemapper
    1.08  MG     03/02/16 Added HDCP support
    1.09  MG     09/03/16 Added XV_HdmiTxSs_SetHdmiMode and XV_HdmiTxSs_SetDviMode
                          Removed reduced blanking support
    1.10  MH     03/15/16 Moved HDCP 2.2 reset from stream up/down callback to
                          connect callback
    1.11  YH     18/03/16 Add XV_HdmiTxSs_SendGenericAuxInfoframe function
    1.12  MH     23/04/16 1. HDCP 1.x driver now uses AXI timer 4.1, so updated
                          to use AXI Timer config structure to determine timer
                          clock frequency
                          2. HDCP 1.x driver has fixed the problem where the
                          reset for the receiver causes the entire DDC peripheral
                          to get reset. Based on this change the driver has been
                          updated to use XV_HdmiTxSs_HdcpReset and
                          XV_HdmiTxSs_HdcpReset functions directly.
                          3. Updated XV_HdmiTxSs_HdcpEnable and
                          XV_HdmiTxSs_HdcpEnable functions to ensure that
                          HDCP 1.4 and 2.2 are mutually exclusive.
                          This fixes the problem where HDCP 1.4 and 2.2
                          state machines are running simultaneously.
    1.13   MH    23/06/16 Added HDCP repeater support.
    1.14   YH    18/07/16 1. Replace xil_print with xdbg_printf.
                          2. XV_HdmiTx_VSIF VSIF global variable local to
                           XV_HdmiTxSs_SendVSInfoframe
                          3. Replace MB_Sleep() with usleep
                          4. Remove checking VideoMode < XVIDC_VM_NUM_SUPPORTED in
                          XV_HdmiTxSs_SetStream to support customized video format
    1.15   YH    25/07/16 Used UINTPTR instead of u32 for BaseAddress
                          XV_HdmiTxSs_CfgInitialize
    1.16   YH    04/08/16 Remove unused functions
                          XV_HdmiTxSs_GetSubSysStruct
    1.17   MH    08/08/16 Updates to optimize out HDCP when excluded.
    1.18   YH    17/08/16 Remove sleep in XV_HdmiTxSs_ResetRemapper
                          Added Event Log
                          Combine Report function into one ReportInfo
    1.19   YH    27/08/16 Remove unused functions XV_HdmiTxSs_SetUserTimerHandler
                          XV_HdmiTxSs_WaitUs
    1.20   MH    08/10/16 Update function call sequence in

                          which sets the Audio Channels
                          accordingly. This fixed is made during v1.2 (2016.1)
    1.21  YH     14/11/16 Added API to enable/disable YUV420/Pixel Repeat Mode
                          for video bridge

                              used
                          Replaced "print" with "xil_printf"
                          Replace Carriage Return () and Line Feed (

    ) order,\
                              where the Carriage Return + Line Feed order is used.

int XV_HdmiTxSs_CfgInitialize | ( | XV_HdmiTxSs * | InstancePtr,
|  | XV_HdmiTxSs_Config * | CfgPtr,
|  | UINTPTR | EffectiveAddr
| ) |  |

This function initializes the video subsystem and included sub-cores.

This function must be called prior to using the subsystem. Initialization includes setting up the instance data for top level as well as all included sub-core therein, and ensuring the hardware is in a known stable state.

Parameters

  InstancePtr | is a pointer to the Subsystem instance to be worked on.
  CfgPtr | points to the configuration structure associated with the subsystem instance.
  EffectiveAddr | is the base address of the device. If address translation is being used, then this parameter must reflect the virtual base address. Otherwise, the physical address should be used.

Returns
  XST_SUCCESS if initialization is successful else XST_FAILURE
