********************************
As you can see in the boot log, when kernel is loading, I get an error for
i2c failure of tda19988.
[ 1.813307] i2c i2c-0: Failed to register i2c client tda998x at 0x70
(-16)
[ 1.820327] i2c i2c-0: of_i2c: Failure registering
/ocp/i2c@44e0b000/tda19988
What's the reason of getting this error?
Thank you,
