Did you check that binding with the dt_binding_check? Something like: make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/mtd/partitions/openwrt,uimage.yaml (you may need arch too, e.g. ARCH=arm64) I think preferred license for yaml (that dt_binding_check checks for) is # SPDX-License-Identifier: GPL-2.0-only OR BSD-2-Clause _______________________________________________ openwrt-devel mailing list [email protected] https://lists.openwrt.org/mailman/listinfo/openwrt-devel
