XV_HDMITXSS_HANDLER_CONNECT - 3.2 English

This interrupt is triggered every time an HDMI TX cable connection or disconnection (HPD level transition) occurs. The callback function must perform the following:

1. Check if the event is cable connected or cable disconnected:

   XV_HdmiTxSs *HdmiTxSsPtr = (XV_HdmiTxSs *)CallbackRef;
   
   HdmiTxSsPtr->IsStreamConnected
   1 - Connected
   0 - Disconnected

2. Enable or disable the differential input clock buffer depending on if cable connection or disconnection occurs, respectively.

   void XVphy_IBufDsEnable(XVphy *InstancePtr, 
                           u8 QuadId, 
                           XVphy_DirectionType Dir,
                           u8 Enable);

3. Detect if the HDMI sink connected is HDMI 2.0 capable and if cable is connected.

   int XV_HdmiTxSs_DetectHdmi20(XV_HdmiTxSs *InstancePtr); 

4. Now, the HDMI sink has been detected, retrieve the sink EDID information, and store it in a local buffer (256 bytes) using the following API:

   int XV_HdmiTxSs_ReadEdid(XV_HdmiTxSs *InstancePtr, u8 *Buffer);
