Subject: [PATCH v2 02/11] ASoC: topology: ABI - Add flags to PCM
Date: Fri,  9 Sep 2016 19:45:27 +0800	[thread overview]
Message-ID: <f99d2b2e874c2aeb1a5f0d76c8e3d21a9d26cd66.1473420558.git.mengdong.lin@linux.intel.com> (raw)
In-Reply-To: <cover.1473420558.git.mengdong.lin@linux.intel.com>

From: Mengdong Lin <mengdong.lin@linux.intel.com>

Add flags to PCM. These flags will be applied to FE (Front End) links.
