I still need to figure out prefixing multiple instances of this Amplifier controls with "Left" and "Right"

FWIW we use the "snd_codec_conf" stuff to add a prefix for each amplifier, so that the controls are not mixed up between instances of the same amp, see e.g.

Thanks Pierre for the inputs.
Am using Documentation/devicetree/bindings/sound/name-prefix.txt for dt and it works!

I will send new set of patches by dropping this patch!

static struct snd_soc_codec_conf codec_conf[] = {
     {
         .dev_name = "sdw:0:25d:711:0:1",
         .name_prefix = "rt711",
