The i2c IP of JH7110 is from Synopsys and the same as the i2c IP in JH7100.
The binding and driver for i2c are already upstream. It works as long as we
add the i2c nodes and configure pins for i2c in device tree. It will simplify
the dependency if we do that.

By the way, I am checking the ISA of U74-MC on JH7110 with someone else.
I will reply you today.
