From: Fabio Estevam Date: Tue, 7 Aug 2012 19:51:34 +0000 (-0300) Subject: ASoC: imx-ssi: Remove mono support X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0865a75d4166bddc533fd50831829ceefb94f9b0;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git ASoC: imx-ssi: Remove mono support Playing a mono track results in incorrect playback rate, ie, the audio is played at a faster rate. Remove mono support in the driver by setting 'channes_min' to dual-channel and this allows mono tracks to be played correctly.
