The devices have an integrated DSP and load diagnostics, and are controlled over I2C. Patch 1 adds the dt-binding, patch 2 the codec driver, patch 3 the ALSA mixer controls documentation, and patch 4 adds the MAINTAINERS entry. Tested on AM62D-EVM with a TAS67CD-AEC daughter card. For setup & test procedures, refer to the GitHub repository.
