Subject: [PATCH v10 8/9] arm64: dts: imx943-evk: Add display support using IT6263
Date: Tue,  6 Oct 2026 12:22:03 +0000	[thread overview]
Message-ID: <20261006-dcif-upstreaming-v10-8-bcfb28de0aae@oss.nxp.com> (raw)
In-Reply-To: <20261006-dcif-upstreaming-v10-0-bcfb28de0aae@oss.nxp.com>

The ITE IT6263 based NXP LVDS to HDMI converter can be attached to the
i.MX943 EVK board LVDS port using the mini-SAS connector. Since this is
the default configuration for the EVK, add support for it here.
