Change additionalProperties to unevaluatedProperties because it refs to touchscreen.yaml. Fix below CHECK_DTBS warnings: arch/arm/boot/dts/nxp/imx/imx6dl-skov-revc-lt6.dtb: touchscreen (resistive-adc-touch): 'touchscreen-y-plate-ohms' does not match any of the regexes: '^pinctrl-[0-9]+$' from schema $id: http://devicetree.org/schemas/input/touchscreen/resistive-adc-touch.yaml# Signed-off-by: Frank Li <Frank.Li@nxp.com> Acked-by: Rob Herring (Arm) <robh@kernel.org> Link: https://lore.kernel.org/r/20250910224402.994046-1-Frank.Li@nxp.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
