Subject: [PATCH v2 2/4] drm/bridge: ti-sn65dsi83: Make enable GPIO optional
Date: Tue, 12 Oct 2021 08:48:41 +0200	[thread overview]
Message-ID: <20211012064843.298104-3-alexander.stein@ew.tq-group.com> (raw)
In-Reply-To: <20211012064843.298104-1-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")
