Subject: [PATCH 3/3] drm/bridge: ti-sn65dsi8: Make enable GPIO optional
Date: Wed, 6 Oct 2021 09:47:13 +0200 [thread overview]
Message-ID: <20211006074713.1094396-3-alexander.stein@ew.tq-group.com> (raw)
In-Reply-To: <20211006074713.1094396-1-alexander.stein@ew.tq-group.com>
The enable signal may not be controllable by the kernel. Make it
optional.
This is a similar to commit bbda1704fc15 ("drm/bridge: ti-sn65dsi86: Make
enable GPIO optional")
