From c7b655ade96a282a4304d68dcb120fcb61f19db2 Mon Sep 17 00:00:00 2001 From: Ranjani Sridharan Date: Tue, 8 Mar 2022 08:43:39 -0800 Subject: [PATCH] ASoC: SOF: Add a tuples array to struct snd_sof_widget MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Add 2 new fields to snd_sof_widget to store an array of tuples defined by struct snd_sof_tuple and the number of tuples. When the topology gets parsed, the tuples associated with a widget will be stored in this array and will be used to construct the IPC structure depending on the IPC version.
