Subject: [PATCH v2 06/11] ASoC: topology: ABI - Define DAI physical PCM data formats
Date: Fri, 9 Sep 2016 19:46:13 +0800 [thread overview]
Message-ID: <cf3caa969a0294d57d9f9e7697cbdfd49c999dc4.1473420558.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>
Define DAI physical PCM data formats for user space, so users can specify
the formats of backends by topology (e.g. the DAI format to set on backend
link init).
The kernel will also refer to these formats.
