From a8035f073cb508a0c1223db2662510575627b41d Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Thu, 11 Jul 2013 14:35:44 +0200 Subject: [PATCH] ASoC: omap-mcpdm: Do not use platform_get_resource_byname() for DMA The DMA resource no longer available via this API when booting with DT. McPDM is only available on OMAP4/5 and both can boot with DT only. Set the dma_data.filter_data to the DMA name which will be used by omap-pcm to request the DMA channel.
