From 30fbd08bca92c70b04b7980c7c4b2835dd0b46ec Mon Sep 17 00:00:00 2001 From: Junkai Cai Date: Wed, 4 Aug 2021 22:16:03 -0700 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 --- soc/swr-mstr-ctrl.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/soc/swr-mstr-ctrl.c b/soc/swr-mstr-ctrl.c index 1637eb75ab..9670476fb9 100644 --- a/soc/swr-mstr-ctrl.c +++ b/soc/swr-mstr-ctrl.c @@ -1767,6 +1767,8 @@ static int swrm_slvdev_datapath_control(struct swr_master *master, bool enable) dev_dbg(&master->dev, "%s: pm_runtime auto suspend triggered\n", __func__); pm_runtime_mark_last_busy(swrm->dev); + if (!enable) + pm_runtime_set_autosuspend_delay(swrm->dev, 80); pm_runtime_put_autosuspend(swrm->dev); } exit: @@ -3411,6 +3413,9 @@ exit: mutex_unlock(&swrm->runtime_lock); trace_printk("%s: pm_runtime: suspend done state: %d\n", __func__, swrm->state); + dev_dbg(dev, "%s: pm_runtime: suspend done state: %d\n", + __func__, swrm->state); + pm_runtime_set_autosuspend_delay(dev, auto_suspend_timer); return ret; } #endif /* CONFIG_PM */
