we have mounted adv7604(decoder) and adv7340(encoder) i2c devices on tx2 interface board. when I am loading adv7604 module I am getting the following kernel messages.

adv7604 0-004c: Handling HPD 0 GPIO
[ 2032.180390] i2c i2c-0: Failed to register i2c client dummy at 0x40 (-16)
[ 2032.187191] adv7611 0-004c: failed to create i2c client 2
[ 2032.192776] adv7604: probe of 0-004c failed with error -12

the device is not getting detected with i2cdetect tool. can anyone please tell me what could be the reason?

any help would be appreciated.

Thanks in Advance,
