[PATCH 2/2] ASoC: Intel: boards: use software node API in Atom boards

Pierre-Louis Bossart pierre-louis.bossart at linux.intel.com
Tue Jun 8 00:35:03 CEST 2021


From: Heikki Krogerus <heikki.krogerus at linux.intel.com>

The function device_add_properties() is going to be removed.
Replacing it with software node API equivalents.
