+From 4f7fcea7402d7d788fe959bc9b7ced86af72d806 Mon Sep 17 00:00:00 2001
+From: R, Dharageswari <dharageswari.r@intel.com>
+Date: Thu, 29 Apr 2010 20:20:22 +0530
+Subject: [PATCH] ADR-Post-Beta-0.05.002.03-2/8-Adding Moorestown Audio Drivers: SST header files
+
+This patch adds the common header files.
+intel_sst_common.h - This header files is private to SST driver and contain the
+common structures like SST ops, SST register offsets, debugging macro,
+sst stream definitions, and Shim register definitions.
+intel_sst_pvt.c - Utility functions used by SST driver and function
+prototypes of common functions are implemented in this file
+
+Signed-off-by: Vinod Koul <vinod.koul@intel.com>
