Subject: [PATCH v2 5/5] DT/arm,gic-v3: add collections-reset-on-suspend property
Date: Thu, 25 Jan 2018 23:38:35 -0800	[thread overview]
Message-ID: <20180126073835.16575-6-dbasehore@chromium.org> (raw)
In-Reply-To: <20180126073835.16575-1-dbasehore@chromium.org>

This boolean property for the GIC-V3-ITS enables resending the MAP
COLLECTIONS commands when resuming for when the state is reset on
suspend.

   resume.
+- collections-reset-on-suspend : Boolean property. If the collections for the
