Hi Dave,
Thanks for your inputs, actually we got a script "ADV7604IO_ADV7604CP_ADV7604AFE_ADV7604HDMI_ADV7341B-VER.1.3c_RevA.txt"reference and used DVI section of this script using which we could make our driver working and it is able to detect different video resolutions.
Then we identified that LLC clock is not coming out from the ADV7604, then we did following configurations and after that we could start getting clock also on LLC pin.
write 0x4c, 0x13, 0x80
write 0x40, 0x33, 0x00
Now, issue is that when we provide output signals of ADV7604 to our capture port of processor and when we start our application we see that the LLC clock on ADV7604 gets almost stop and also it got too much attenuation.
Basically we are capturing RGB and converting it to YPbPr 422.
