scripts/dtc/update-dtc-source.sh\n\nAs for (1), the first and third chunks were already applied. The second \none (below) seemed to be N/A:\n\n-always-$(CHECK_DT_BINDING) += $(patsubst \n$(srctree)/$(src)/%.yaml,%.example.dt.yaml, $(CHK_DT_DOCS))\n+always-$(CHECK_DT_BINDING) += $(patsubst \n$(srctree)/$(src)/%.yaml,%.example.dtb, $(CHK_DT_DOCS))\n\nAbout (2), it was already applied as well, nothing to be done there.\n\nAbout (3), I might be wrong because I'm not familiar with this file, but \nI skipped this chunk because it also seemed to be N/A:\n\n-$(obj)/%.dtb: $(src)/%.dts $(DTC) FORCE\n- $(call if_changed_dep,dtc)\n-\n-$(obj)/%.dtbo: $(src)/%.dts $(DTC) FORCE\n- $(call if_changed_dep,dtc)\n-\n\nanother chunk I skipped in (3), because it seemed to be partially \napplied (e.g., the || true and the ifneq on top):\n\n+ifneq ($(CHECK_DTBS)$(CHECK_DT_BINDING),)\n DT_CHECKER ?= dt-validate\n DT_CHECKER_FLAGS ?= $(if $(DT_SCHEMA_FILES),-l $(DT_SCHEMA_FILES),-m)\n DT_BINDING_DIR := Documentation/devicetree/bindings\n DT_TMP_SCHEMA := $(objtree)/$(DT_BINDING_DIR)/processed-schema.json\n\n quiet_cmd_dtb_check = CHECK $@\n- cmd_dtb_check = $(DT_CHECKER) $(DT_CHECKER_FLAGS) -u \n$(srctree)/$(DT_BINDING_DIR) -p $(DT_TMP_SCHEMA) $@\n+ cmd_dtb_check = $(DT_CHECKER) $(DT_CHECKER_FLAGS) -u \n$(srctree)/$(DT_BINDING_DIR) -p $(DT_TMP_SCHEMA) $@ || true\n+endif\n\nbut now I'm reconsidering...please let me know what you think.\n\nStill regarding (3), I skipped the 4th chunk (already applied) and this \nlast one (below, which now I'm also reconsidering):\n\n+$(obj)/%.dtbo: $(src)/%.dts $(DTC) FORCE\n+ $(call if_changed_dep,dtc)\n+\n\nFinally, (4) and (5) applied fine, so not much to say about them.\n\nHonestly, I'm not familiar with the way you sync those files (how, when, \nwhere, etc), so I'm not sure how much I can be of help here.\n\nI hope this clarifies my backport, but please reach back to me if it didn't.","headers":{"Return-Path":"","X-Original-To":"incoming@patchwork.ozlabs.org","Delivered-To":"patchwork-incoming@legolas.ozlabs.org","Authentication-Results":["legolas.ozlabs.org;\n\tdkim=pass (2048-bit key;\n unprotected) header.d=bootlin.com header.i=@bootlin.com header.a=rsa-sha256\n header.s=dkim header.b=V6Pn7wAe;\n\tdkim-atps=neutral","legolas.ozlabs.org;\n spf=pass (sender SPF authorized) smtp.mailfrom=lists.denx.de\n (client-ip=2a01:238:438b:c500:173d:9f52:ddab:ee01;
