[PATCH 1/2] ASoC: pcm512x: Adds bindings for TAS575x devices
The TAS5754/6 power amplifiers use the same pcm512x driver with only minor restictions described in the bindings document.

Is there anything new here? Just a different compatible doesn't justify another example.
With that dropped,

Thanks for feedback. Actually, there is nothing really new. More to show the reduced availability of GPIOs. I'm preparing a new version of the patch and I will drop the example.
