From a23dc694828e3de96bf18e20459ba885ba91cb29 Mon Sep 17 00:00:00 2001 From: Shawn Guo Date: Fri, 16 Mar 2012 16:56:38 +0800 Subject: ASoC: imx: merge sound/soc/imx into sound/soc/fsl Freescale PowerPC and ARM/IMX families share the same SSI IP block. The patch merges sound/soc/imx into sound/soc/fsl, so that the possible code sharing and consolidation can happen. This is a plain merge, except that menuconfig SND_POWERPC_SOC is added in Kconfig for PowerPC platform as a correspondence to SND_IMX_SOC for IMX platform.
