Subject: [PATCH 04/17] ABI: sysfs-devices-power: document some RPM statistics
Date: Mon, 27 Sep 2021 15:59:37 +0200	[thread overview]
Message-ID: <d5524b966d081c650121c4c496c2f7ab3df524e9.1632750608.git.mchehab+huawei@kernel.org> (raw)
In-Reply-To: <cover.1632750608.git.mchehab+huawei@kernel.org>

Changeset 8d4b9d1bfef1 ("PM / Runtime: Add runtime PM statistics (v3)")
added runtime_active_time and runtime_suspended_time, in order
to allow powertop to identify the amount of time a device is
active/suspended.

Add an ABI description for those.
