From 9f86aea992568c2b4db78c80ff9508af9e050ff7 Mon Sep 17 00:00:00 2001 From: Chancel Liu Date: Fri, 10 Jul 2026 12:13:33 +0900 Subject: [PATCH] ASoC: fsl: imx-card: Skip sysclk reset for active DAIs in shutdown In a full-duplex setup, when one direction (playback or capture) is closed while the other is still running, imx_aif_shutdown() was unconditionally calling snd_soc_dai_set_sysclk() with rate=0 for all cpu/codec DAIs, which would disable the clock still needed by the active stream. Add snd_soc_dai_active() checks before clearing sysclk so that only truly inactive DAIs have their clocks reset.
