From 15a55ec2f8b956d6aa0dd948c907e13db7978c6e Mon Sep 17 00:00:00 2001 From: Ranjani Sridharan Date: Wed, 4 Feb 2026 10:18:28 +0200 Subject: [PATCH] ASoC: SOF: ipc4-topology: Add new tokens for pipeline direction MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Parse the pipeline direction from topology. The direction_valid token is required for backward-compatibility with older topologies that may not have the direction set for pipelines. This will be used when setting up pipelines to check if a pipeline is in the same direction as the requested params and skip those in the opposite direction like in the case of echo reference capture pipelines during playback.
