From: Sameer Pujar <spujar@xxxxxxxxxx> There can be customized sound cards which are based on generic audio graph. In such cases most of the stuff is reused from generic audio graph. To facilitate this, refactor audio graph schema into multiple files and the base schema can be reused for specific sound cards. The graph card nodes and port nodes are separate entities, so they should be separate schemas.
