Subject: [PATCH v2 3/4] ASoC: dapm: Introduce DAPM_DOUBLE dual channel control type
Date: Wed,  2 Nov 2016 15:36:00 +0800	[thread overview]
Message-ID: <20161102073601.8659-4-wens@csie.org> (raw)
In-Reply-To: <20161102073601.8659-1-wens@csie.org>

A DAPM_DOUBLE control type can be used for dual channel mixer input
selectors / mute controls in one register, possibly toggling both
channels together.

The control is meant to be shared by 2 widgets, 1 for each channel,
such that the mixer control exposed to userspace remains a combined
stereo control.
