From bcd6da7bfd1bc3e9d5f8887967ec3d550ce56c70 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Fri, 14 Sep 2012 15:05:57 +0300 Subject: [PATCH] ASoC: OMAP: mcbsp, mcpdm, dmic, hdmi: Set dma_data at startup time Set the dma_data for the stream (snd_soc_dai_set_dma_data) at dai_startup time so omap-pcm will have access to the needed information regarding to the DMA channel earlier. This is needed for the clean dmaengine support.
