Subject: [PATCH v1 1/3] arm64: dts: imx8mq: Add NWL MIPI DSI controller
Date: Wed, 29 Jul 2020 14:19:43 +0200 [thread overview]
Message-ID: <41adfe49c75d8bb261dc8d481e9bb537f6699cb4.1596025057.git.agx@sigxcpu.org> (raw)
In-Reply-To: <cover.1596025057.git.agx@sigxcpu.org>
Add a node for the Northwest Logic MIPI DSI IP core, "disabled" by
default. This also adds the necessary port to LCDIF.
Signed-off-by: Guido Günther <agx@sigxcpu.org>
