tlv320aic23 chip control interface may work in either I2C or SPI mode depending on the MODE pin state. Functionality and register layout are independent of the control mode. Implement bus-specific parts as separate modules. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>
