Subject: [PATCH 0/2] cpuidle: Fix runtime PM based cpuidle for s2idle
Date: Wed, 29 Sep 2021 16:44:49 +0200 [thread overview]
Message-ID: <20210929144451.113334-1-ulf.hansson@linaro.org> (raw)
Maulik Shah reported problems to me around the s2idle support in the
cpuidle-psci driver. More precisely, calls to pm_runtime_get|put fails during
system wide suspend, because runtime PM gets disabled by the PM core.
This small series intends to fix the problem. More details in the commit
messages.
Kind regards
Ulf Hansson
