Thank you very much. I will change the following content in the next patch:
Add two properties, the "awinic,audio-channel" property and the
"awinic,sync-flag". The "awinic,audio-channel" is used to make 
different PA load different configurations, the "awinic,sync-flag"
is used to synchronize the phases of multiple PA. These two properties 
will be read by the corresponding driver, so that the multi-PA to 
achieve better playback effect.
