Subject: [PATCH v6 8/8] ARM: dts: sun8i-h3: Add Video Engine and reserved memory nodes
Date:   Wed, 25 Jul 2018 12:02:56 +0200
Message-Id: <20180725100256.22833-9-paul.kocialkowski@bootlin.com>
In-Reply-To: <20180725100256.22833-1-paul.kocialkowski@bootlin.com>
References: <20180725100256.22833-1-paul.kocialkowski@bootlin.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

This adds nodes for the Video Engine and the associated reserved memory
for the H3. Up to 96 MiB of memory are dedicated to the CMA pool.
