Subject: [PATCH 2/2] ARM: dts: iwg22d-sodimm: disable lcd for extension board
Date: Wed, 29 Jan 2020 18:40:53 +0000 [thread overview]
Message-ID: <1580323253-3281-3-git-send-email-marian-cristian.rotariu.rb@bp.renesas.com> (raw)
In-Reply-To: <1580323253-3281-1-git-send-email-marian-cristian.rotariu.rb@bp.renesas.com>
The two variants of the iW-G22D should be mutually exclusive, therefore
this patch disables the RGB LCD display when the HDMI extension board is
used.
