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.
static struct snd_soc_codec_conf codec_conf[] = {
{
.dev_name = "sdw:0:25d:711:0:1",
.name_prefix = "rt711",
},
{
.dev_name = "sdw:1:25d:1308:0:0",
.name_prefix = "rt1308-1",
},
{
.dev_name = "sdw:2:25d:1308:0:2",
.name_prefix = "rt1308-2",
},
{
.dev_name = "sdw:3:25d:715:0:1",
.name_prefix = "rt715",
},
};
