From 2c4cf17a52f04fbe929977252d5b8ab81d2c6e9b Mon Sep 17 00:00:00 2001 From: Wolfram Sang Date: Fri, 25 Mar 2011 16:51:44 +0100 Subject: ASoC: imx: set watermarks for mx2-dma They got accidently removed by f0fba2a (ASoC: multi-component - ASoC Multi-Component Support). Reintroduce them and get rid of the superfluous defines because the fiq-driver has its own hardcoded values.

This bug is triggered via SDL. This patch adds check for prtd->dma_ch to __pxa2xx_pcm_prepare and cleans prtd->params, so now it works properly.
