Subject: [PATCH v3 3/5] DT/arm,gic-v3-its: add reset-on-suspend property
Date: Mon, 29 Jan 2018 17:00:05 -0800 [thread overview]
Message-ID: <20180130010007.256564-4-dbasehore@chromium.org> (raw)
In-Reply-To: <20180130010007.256564-1-dbasehore-F7+t8E8rja9g9hUCZPvPmw@public.gmane.org>
This adds documentation for the new reset-on-suspend property. This
property enables saving and restoring the ITS for when it loses state
in system suspend.
