Thanks Mark for the review, On 04/08/2021 19:01, Mark Brown wrote: > On Tue, Aug 03, 2021 at 01:54:01PM +0100, Srinivas Kandagatla wrote: > >> compatible: >> - const: qcom,q6asm-dais >> + enum: >> + - qcom,q6asm-dais >> + - qcom,q6apm-dais > > What do these two compatibles mean? > Old Elite QDSP framework has service called "Audio Stream Manager" aka q6asm which is responsible for managing the PCM/Compressed streams and Pre Processing. With New AudioReach framework this functionality is managed by "Audio Process Manager" aka q6apm. As we are using rpmsg device model to link these audio service channels with linux devices so we endup with prefixing the compatibles with service names(like q6afe, q6asm, q6adm, q6apm, q6prm ...). --srini
