From 6584cb8825e4c74915a5a13756b1902523391d78 Mon Sep 17 00:00:00 2001 From: Sascha Hauer Date: Wed, 6 Jul 2011 11:18:33 +0200 Subject: ARM i.MX dma: Fix burstsize settings dmaengine expects the maxburst parameter in words, not bytes. The imxdma driver and its users do this wrong. Fix this. As a side note the imx-pcm-dma-mx2 driver was 'fixed' to work with imx-dma. This broke the driver with imx-sdma support which correctly takes the maxburst parameter in words. This patch puts the sdma based sound back to work.
