From: Weidong Wang wangweidong.a@awinic.com

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, allowing multi-PA to achieve better playback effect.
