Subject: [PATCH v3 2/2] arm64: dts: renesas: Add HiHope RZ/G2M board with idk-1110wr display
Date: Tue, 10 Mar 2020 20:41:59 +0000 [thread overview]
Message-ID: <1583872919-7757-3-git-send-email-prabhakar.mahadev-lad.rj@bp.renesas.com> (raw)
In-Reply-To: <1583872919-7757-1-git-send-email-prabhakar.mahadev-lad.rj@bp.renesas.com>
From: Fabrizio Castro <fabrizio.castro@bp.renesas.com>
The HiHope RZ/G2M is advertised as compatible with panel idk-1110wr
from Advantech, however the panel isn't sold alongside the board.
A new dts, adding everything that's required to get the panel to
work the HiHope RZ/G2M, is the most convenient way to support the
HiHope RZ/G2M when it's connected to the idk-1110wr.
