Subject: [PATCH 2/7] drm: rcar-du: Add r8a7742 support
Date:   Fri,  7 Aug 2020 18:49:49 +0100
Message-Id: <20200807174954.14448-3-prabhakar.mahadev-lad.rj@bp.renesas.com>
In-Reply-To: <20200807174954.14448-1-prabhakar.mahadev-lad.rj@bp.renesas.com>
References: <20200807174954.14448-1-prabhakar.mahadev-lad.rj@bp.renesas.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add direct support for the r8a7742 (RZ/G1H).

The RZ/G1H shares a common, compatible configuration with the r8a7790
(R-Car H2) so that device info structure is reused, the only difference
being TCON is unsupported on RZ/G1H (Currently unsupported by the driver).
