Subject: [PATCH 06/15] ASoC: cs42l42: Provide finer control on playback path
Date: Tue, 2 Mar 2021 17:04:45 +0000	[thread overview]
Message-ID: <20210302170454.39679-7-tanureal@opensource.cirrus.com> (raw)
In-Reply-To: <20210302170454.39679-1-tanureal@opensource.cirrus.com>

Removing cs42l42_hpdrv_evt that enables the entire chain and replace by
a set of widgets that can better define the codec
