That would require to duplicate the setting from imx8mp.dtsi. Is this really intended? imx8mp-tqma8mpqs-mb-smarc-2-lvds-g133han01.dtso:51.10-55.5: Warning (unit_a= ddress_vs_reg): /fragment@3/__overlay__/ports/port@1: node has a unit name,= but no reg or ranges property imx8mp-tqma8mpqs-mb-smarc-2-lvds-g133han01.dtso:57.10-61.5: Warning (unit_a= ddress_vs_reg): /fragment@3/__overlay__/ports/port@2: node has a unit name,= but no reg or ranges property IMHO this warning is not suitable for .dtbo, while it is for .dtb (with applied overlays). The .dtbo doesn't have all the information.
