Subject: [PATCH 3/3] ASoC: simple-card: Read pin switches conf from devicetree
Date: Sat, 20 Apr 2019 12:45:53 +0200	[thread overview]
Message-ID: <20190420104553.5071-3-paul@crapouillou.net> (raw)
In-Reply-To: <20190420104553.5071-1-paul@crapouillou.net>

When the routing path between a widget (e.g. "Speaker") and the codec
goes through an external amplifier, having a pin switch for this widget
allows the amplifier to be disabled when the widget is not to be used
(e.g. when using headphones).
