From 5b1fd5953199b448060ced40b3e000091c4acdc0 Mon Sep 17 00:00:00 2001 From: Soumya Managoli Date: Mon, 24 Apr 2023 11:32:43 +0530 Subject: [PATCH] soc: reduce the auto suspend timeout when swr event finished the APSS would suspend within ~120ms after audio off, if system suspend swrm_suspend() is called before swrm_runtime_suspend. The clock stop sequence require writing IPC and expect interrupt, which would stop the APSS to be suspended. Reduce the auto suspend time specifically when swr event is done can call the swrm_runtime_suspend Change-Id: Iee0c9143d65e5a8e68a8e20ab73bea9def1920bd Signed-off-by: Junkai Cai Signed-off-by: Soumya Managoli --- soc/swr-mstr-ctrl.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) diff --git a/soc/swr-mstr-ctrl.c b/soc/swr-mstr-ctrl.c index 752d5c2b2940..2cd057c34b71 100644 --- a/soc/swr-mstr-ctrl.c +++ b/soc/swr-mstr-ctrl.c @@ -1,7 +1,7 @@ // SPDX-License-Identifier: GPL-2.0-only /* * Copyright (c) 2015-2021, The Linux Foundation.
