Thank you very much. I would like to add a sound-channel property to awinic,aw87390.yaml
This property is used to distinguish between multiple PA's in order to
load different configurations for different PA's

Thank you very much. I will modify it to
"return dev_err_probe(&i2c->dev, PTR_ERR(aw87390->regmap), "failed to init regmap: %d\n", ret);"
