Subject: [PATCH 3/4] drm/bridge: ti-sn65dsi86: find any enabled endpoint
Date: Sat, 7 Dec 2019 12:35:52 -0800 [thread overview]
Message-ID: <20191207203553.286017-4-robdclark@gmail.com> (raw)
In-Reply-To: <20191207203553.286017-1-robdclark@gmail.com>
From: Rob Clark <robdclark@chromium.org>
This bridge is used on a number of devices that can have one of multiple
different panels installed. The firmware will enable the panel driver
node for the panel that is actually installed. So the bridge should ask
drm_of_find_panel_or_bridge() to find the endpoint for the enabled
panel.
