From 6db1c6ba9544e99778e0fdebe2d62c917fe1811c Mon Sep 17 00:00:00 2001 From: Srinivas Kandagatla Date: Sat, 16 May 2015 13:32:34 +0100 Subject: ASoC: qcom: remove hardcoded dma channel This patch removes hardcoded dma channel value in lpass driver, Now the dma channel allocation happens in the SOC specific layer. This will allow different LPASS integrations to use the lpass driver in more generic way.
