Subject: [PATCHv1 5/7] drm/panel: sitronix-st7789v: make reset GPIO optional
Date: Sat, 18 Mar 2023 00:23:53 +0100 [thread overview]
Message-ID: <20230317232355.1554980-6-sre@kernel.org> (raw)
In-Reply-To: <20230317232355.1554980-1-sre@kernel.org>
The reset pin might not be software controllable from the SoC,
so make it optional.
