Subject: [PATCH 5/8] ARM: dts: imx6ul: Add parallel display DT overlay for TQMa6ULx
Date: Fri, 2 Oct 2026 10:14:06 +0200 [thread overview]
Message-ID: <20261002081417.2092471-6-alexander.stein@ew.tq-group.com> (raw)
In-Reply-To: <20261002081417.2092471-1-alexander.stein@ew.tq-group.com>
Both displays are attached on X4 and differ only in display settings.
Note: Due to hardware wiring a 24-Bit bus-width has to be used.
