From 7006d20e5e9d25c079a82e2bc0ea7e292fdea6e6 Mon Sep 17 00:00:00 2001 From: Ranjani Sridharan Date: Mon, 14 Mar 2022 13:05:06 -0700 Subject: ASoC: SOF: Introduce IPC3 ops MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add the IPC ops including the topology-related IPC ops for the current version (IPC3, named after the current SOF firmware ABI major version 3.0) of IPC supported by the SOF firmware and set it as default. The topology IPC ops and the widget ops within the topology IPC ops are both mandatory. With the introduction of IPC3 ops, we define the list of tokens pertaining to the AIF_IN/AIF_OUT widgets. Then these tokens are parsed during topology parsing and saved as part of the swidget tuples array. Once topology parsing is complete, these tokens will be applied to create the IPC structure for the host component based on the topology widget_setup op in ipc3_tplg_ops.
