Hello everyone, You will find in this series the support of Texas Instrument's DAC PCM1789. This DAC is very minimalist and is similar to PCM1792a except for some differences in registers. Series based on asoc tree, "for-next" branch (last commit 130c3888dfdc). It is important to notice that this DAC needs to always have clocks enabled (even without any data) otherwise it will be in a "desynchronized" state and can not send data correctly. This issue has been solved by performing a reset each time a sound is played (see patch 04). This reset can produce a "pop" noise. Thank you in advance for any review.
