+Subject: [PATCH] ADR-Post-Beta-0.05.002.03-5/8-Moorestown Audio Drivers: SST stream ops module
+
+This adds the stream module which contains the function for stream
+operations & control. For a stream the control and data are two major parts.
+This module implements the control (play/pause/resume/stop/free/alloc)
+for a stream. It also implements data play/capture frames where buffers are
+sent/received to FW. The objective of SST driver is to achieve Low power
+playback by utilizing DSP as much aspossible. So SST gets large music
+buffers from player/middleware and sends them to FW in a scatter gather list.
+The FW decodes and renders them, while IA can goto low power states
