+description:
+ The TAS2781 is a mono, digital input Class-D audio amplifier
+ optimized for efficiently driving high peak power into small
+ loudspeakers. Integrated an on-chip DSP supports Texas Instruments
+ Smart Amp speaker protection algorithm. The integrated speaker
+ voltage and current sense provides for real time
+ monitoring of loudspeaker behavior.

I did not get anything else, only this patch.

You named it v1, so this changelog or naming seems incorrect. There was
v5 or v6, right? What changed here? There were several comments to your
patches. Since nothing changed, I assume you need to implement them again.
Please implement all the comments Rob asked. Then write a changelog
describing what you changed.
Best regards,
Krzysztof
