X-BeenThere: alsa-devel@alsa-project.org X-Mailman-Version: 2.1.14 Precedence: list List-Id: "Alsa-devel mailing list for ALSA developers - http://www.alsa-project.org" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , MIME-Version: 1.0 Errors-To: alsa-devel-bounces@alsa-project.org Sender: alsa-devel-bounces@alsa-project.org X-Virus-Scanned: ClamAV using ClamSMTP This patch adds DT bindings required for msm8916 codec which is integrated in msm8916 and apq8016 SOCs. Codec IP is divided into two parts, first analog which is integrated in pmic pm8916 and secondly digital part which is integrated into application processor. Codec register controls are also split across pmic an lpass. Analog part is controlled via spmi bus to pmic, registers on the Application processor are memory mapped.
