[PATCH v8 8/9] arm64: dts: imx943-evk: Add display support using IT6263
Posted by Laurentiu Palcu 4 weeks ago 
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.

Since the LVDS to HDMI converter can be attached or detached to the EVK
board, it would be appropriate to use a DT overlay instead?

Maybe, change the node name to be "hdmi" to align with the nodes in
imx8mp-evk-lvds{0,1}-imx-lvds-hdmi-common.dtsi.
