From 2b009fa0823c1510700fd17a0780ddd06a460fb4 Mon Sep 17 00:00:00 2001 From: Ranjani Sridharan Date: Tue, 7 Mar 2023 16:04:33 +0200 Subject: [PATCH] ASoC: SOF: Intel: hda: Unify DAI drv ops for IPC3 and IPC4 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Define the post_trigger DMA op for IPC3 and unify the DAI driver ops for IPC3 and IPC4 for HDA DAI's. Also, use the post_trigger op to stop the paused streams properly in the hda_dai_suspend() function. This fixes the suspend while paused case for IPC4 because previously we weren't resetting the pipeline when suspending the system with some paused streams.
