Subject: [PATCH 3/3] ARM: logicpd-torpedo-37xx-devkit-28: Reference new DRM panel
Date: Tue, 17 Sep 2019 11:12:13 -0500 [thread overview]
Message-ID: <20190917161214.2913-3-aford173@gmail.com> (raw)
In-Reply-To: <20190917161214.2913-1-aford173@gmail.com>
With the removal of the panel-dpi from the omap drivers, the
LCD no longer works. This patch points the device tree to
a newly created panel named "logicpd,type28"
Fixes: 8bf4b1621178 ("drm/omap: Remove panel-dpi driver")
Signed-off-by: Adam Ford <aford173@gmail.com>
