The attach method does not check that it is talking to a real device, trusting the device tree to have the correct address on the I2C bus.

Oleksandr Tymoshenko did the rockchip sound drivers. rk3328codec is for 
rockpro64 and es8316 is for the pinebook pro if memory serves me. Which 
one did you test?
