Subject: [PATCH 2/2] ARM: dts: opos6uldev: use OF graph to describe the display
Date:   Tue, 17 Jul 2018 09:23:18 +0200
Message-Id: <20180717072318.18730-2-sebastien.szymanski@armadeus.com>
In-Reply-To: <20180717072318.18730-1-sebastien.szymanski@armadeus.com>

MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

To make use of the new eLCDIF DRM driver OF graph description is
required. Describe the display using OF graph nodes.
