From 9ee7ef31b5a07cdca88cae023c613e045af935b9 Mon Sep 17 00:00:00 2001 From: Chen-Yu Tsai Date: Wed, 2 Nov 2016 15:36:00 +0800 Subject: ASoC: dapm: Introduce DAPM_DOUBLE dual channel control type 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.
