Subject: [PATCH v2 04/12] ASoC: SOF: sof-audio: add helpers for widgets, kcontrols and dai config set up
Date: Fri, 17 Sep 2021 17:36:51 +0300	[thread overview]
Message-ID: <20210917143659.401102-5-daniel.baluta@oss.nxp.com> (raw)
In-Reply-To: <20210917143659.401102-1-daniel.baluta@oss.nxp.com>

From: Ranjani Sridharan <ranjani.sridharan@linux.intel.com>

Refactor the existing code to use helper functions to
set up/free widgets, send dai config and set up kcontrols for
widgets. These will be reused later on for setting up widgets in
the connected DAPM widgets list for a particular PCM when the
dynamic pipeline feature is implemented.
