From a5ba725e9dc928832ba97a4418e36fef8d0244c6 Mon Sep 17 00:00:00 2001 From: Ranjani Sridharan Date: Tue, 26 Apr 2022 10:17:41 -0700 Subject: [PATCH] ASoC: SOF: topology: Skip parsing DAI link tokens if not needed MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Do not parse these tokens if they are not defined in the IPC version specific token list. In the case of IPC4 with HDA topologies for example, no DAI link specific tokens need to be added in topology.
