Subject: [PATCH] ASoC: cs4265: Add a MIC pre. route
Date: Mon, 24 Sep 2018 09:08:35 +1000 [thread overview]
Message-ID: <20180923230835.18483-1-flatmax@flatmax.org> (raw)
The cs4265 driver is missing a microphone preamp enable.
This patch enables/disables the microphone preamp when mic
selection is made using the kcontrol.
