Subject: [PATCH v3 05/19] drm/panel: sitronix-st7789v: make reset GPIO optional
Date: Fri, 14 Jul 2023 03:37:42 +0200 [thread overview]
Message-ID: <20230714013756.1546769-6-sre@kernel.org> (raw)
In-Reply-To: <20230714013756.1546769-1-sre@kernel.org>
The reset pin might not be software controllable from the SoC,
so make it optional.
