Prusty" Subject: [alsa-devel] [PATCH v3 5/8] ASoC: Intel: Skylake: Add topology core init and handlers 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 The SKL driver does not code DSP topology in driver. It uses the newly added ASoC topology core to parse the topology information (controls, widgets and map) from topology binary. Each topology element passed private data which contains information that driver used to identify the module instance within firmware and send IPCs for that module to DSP firmware along with parameters. This patch adds init routine to invoke topology load and callback for topology creation. Signed-off-by: Jeeja KP Signed-off-by: Subhransu S.
