Commit 9f79c0289fa4b02544c6a51c789c84edd6a479fc ("audio: add support for philips tda1543 dac chip") new simple driver for the old well known philips tda1543 dac chip.
Hello,
We would like to contribute with an audio codec file for the well known Philips TDA1543 dac chip. We have already made a PR for Raspbian with Raspberry Pi specific driver that is well suited together with this codec. We have already got OK confirmation for our PR request and we just need to upstream this codec to finalize the system for our new commersial dac module for Raspberyy PI.

Thanks!
