 * Based on sound/soc/codecs/twl4030.c by Steve Sakoman
 *
 * This file provides stub codec that can be used on OMAP3530 evm to
 * send/receive voice samples to/from WL1271 Bluetooth chip over PCM interface.
 * The Bluetoothchip codec interface is configured by HCI commands. ALSA is
 * configured and aligned to the codec interface.
