From 6945156a677abdc51318f214b0380199204ab6ba Mon Sep 17 00:00:00 2001 From: Mengdong Lin Date: Fri, 4 Nov 2016 07:05:53 +0800 Subject: [PATCH] topology: ABI - Update stream caps and PCM objects to ABI v5 Here are the ABI updates for PCM (Front DAI & DAI link) objects: - add sig_bits to stream caps. - add flags and private data to PCM. The kernel can handle the ABI update in a backward compatible way with the patch "ASoC: topology: Make PCM backward compatible from ABI v4".
