+Subject: [PATCH] scripts/dtc: drop yaml in DT validation
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The build issues found in dtc/yamltree were partially mitigated by a
+previous commit (807bcd844a: "scripts/dtc: Fix pkg-config behavior under
+sysroot"), but upstream dtc simply disabled yaml, and the same should be
+done here in order to permanently avoid those issues.
+
+Backport the change below from Linux v5.18 [1]:
+
+ef8795f3f1c ("dt-bindings: kbuild: Use DTB files for validation")
+
+I tested this patch with a couple Yocto builds: u-boot and u-boot-tools,
+using the current master branch (rev. "c53b0708f9"), having removed
+libyaml-native from u-boot-tools's dependencies.
