From dc31e741db49e35e8b99d293dcc7afbbe9418fa7 Mon Sep 17 00:00:00 2001 From: Mengdong Lin Date: Tue, 26 Jul 2016 14:32:18 +0800 Subject: ASoC: topology: ABI - Add the types for BE DAI Define the type and ABI struct for Backend DAIs. Add the number of BE DAIs to manifest, and some reserved fields for future extensions. Pump the version number to 5. Topology core will check size of ABI objects to detect version mismatch between user space and kernel.
