From d65a14587a9be853a887a1407db133df1fb68e29 Mon Sep 17 00:00:00 2001 From: Daniel Mack Date: Mon, 12 Aug 2013 10:42:39 +0200 Subject: [PATCH] ASoC: pxa: use snd_dmaengine_dai_dma_data Use snd_dmaengine_dai_dma_data for passing the dma parameters from clients to the pxa pcm lib. This does no functional change, it's just an intermedia step to migrate the pxa bits over to dmaengine. The calculation of dcmd is a transition hack which will be removed again in a later patch. It's just there to make the transition more readable.
