From: Chen-Yu Tsai Date: Wed, 2 Nov 2016 07:36:01 +0000 (+0800) Subject: ASoC: dapm: Introduce DAPM_DOUBLE_R dual channel dual register control type X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=02866eab0f0d88c4b6a68de72022c2b26f0359b5;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git ASoC: dapm: Introduce DAPM_DOUBLE_R dual channel dual register control type A DAPM_DOUBLE_R control type can be used for dual channel mixer input selectors / mute controls across 2 registers, 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.
