From 8ef1439c51048b9359a8d1be2360dd4cd9848a77 Mon Sep 17 00:00:00 2001 From: Ranjani Sridharan Date: Mon, 14 Mar 2022 13:05:19 -0700 Subject: [PATCH] ASoC: SOF: topology: Make widget binding IPC agnostic MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Make widget binding in the topology parser IPC agnostic by introducing a new op, bind_event, in struct ipc_tplg_widget_ops. Also set the op for all widget types in the IPC3 topology ops.
