To: alsa-devel; +Cc: Takashi Iwai, Mengdong Lin, Mark Brown, Liam Girdwood
From: Mengdong Lin <mengdong.lin@intel.com>
Define structures that can be used by applications to directly build topology
data instead of using text files. The application will build up the topology
data by populating the template structures for each object type and then
registering the template with the topology core.
