    I want to configure ADV7611 to generate interrupt when video source is connected to HDMI connector.
    
 
    As TMDS clock will be locked to input clock when video source is connected, so I thought based on TMDS clock lock we can conclude video source is connected or not.
    
 
    During free run mode also TMDS clock will be locked?
    
 
    After going through ADV7611 register manual, TMDSPLL_LCK_A_MB1/TMDSPLL_LCK_A_MB2 are used to configure INT1/INT2 for TMDSPLL. In addition to these registers any other registers I have to configure to receive interrupt when TMDS clock locked? 
    
 
    These interrupts are edge triggered or level triggered?

      Besides having the interrupt mask register set as you've mentioned above, you need to set up the interrupt pin as described in the hardware users guide.  See INTRQ_DUR_SEL and INTRQ_OP_SEL.  Several different options exist.  You can also manually trigger and interrupt with MPU_STIM_INTRQ register
