Subject: [PATCH v3 3/3] ALSA: topology: Export ID types for TLV controls.
Date: Fri, 29 May 2015 19:06:15 +0100 [thread overview]
Message-ID: <1432922775-6583-3-git-send-email-liam.r.girdwood@linux.intel.com> (raw)
In-Reply-To: <1432922775-6583-1-git-send-email-liam.r.girdwood@linux.intel.com>
Make sure userspace can define TLV controls for topology using the correct
type numbers and channel mappings.
