I got those new dtbs check errors:
+	from schema $id: http://devicetree.org/schemas/arm/amlogic/amlogic,meson-gx-ao-secure.yaml#
+/arch/arm64/boot/dts/amlogic/meson-axg-jethome-jethub-j110-rev-2.dtb: ao-secure@140: 'secure-monitor' does not match any of the regexes: 'pinctrl-[0-9]+'

and on other files.

Please update the bindings,

Thanks,
Neil
