From: Jeeja KP Date: Thu, 8 Dec 2016 08:11:14 +0000 (+0530) Subject: ASoC: Intel: Skylake: Configure DMA in PRE_PMD handler of Mixer X-Git-Tag: v4.11-rc1~100^2~8^2~13^2~70 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=bb704a737cecc1c4c9f1b0251aa79d8276308ccc;p=karo-tx-linux.git ASoC: Intel: Skylake: Configure DMA in PRE_PMD handler of Mixer If system is suspended when PCM was paused/stopped, restart doesn't configure DMA as it is we are in Pause state and results in IO error eventually. Configure host/link DMA before initializing DSP Gateway copier module instead of DAI prepare(). So moved DMA configuration to mixer PRE_PMD widget handler instead of DAI prepare. This uses previously added new API to do the configuration and removes old DAI prepare code.
