Subject: [PATCH 0/2] ASoC: audio-graph-card: support external amplifier with DAPM widget
Date: Thu, 29 Jun 2017 21:26:36 +0800 [thread overview]
Message-ID: <1498742798-3128-1-git-send-email-shawnguo@kernel.org> (raw)
From: Shawn Guo <shawn.guo-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>
It's basically the result of discussion around how external amplifier
controlled by GPIO should be supported by audio card, that uses generic
machine driver like audio-graph-card.
The patch series updates audio-graph-card bindings and driver to support
DAPM widget and audio routing, and then based on that, creates an output
driver widget with event to control the amplifier via GPIO.
