This series switches the kernel's DT schema validation from YAML encoded DT files to using DTB files directly. See patch 2 for the full reasoning of why. The diffstat also shows this is a nice simplification (at least from the kernel side). Patch 1 is further reworking of how DT_SCHEMA_FILES works and builds on [1]. Overall, the build time is about the same (still slow) though we do save a dtc call for dtbs_check. Extracting the type information is not cached in any way, so there's some opportunity for a slight optimization there. Switching to DTB validation found various issues in the bindings and examples. Patches for those issues have already been posted and applied over the last month or so. v2: - Drop processed-schema.json dependency when building 'dtbs' - Don't allow override of DT_TMP_SCHEMA Rob [1] https://lore.kernel.org/all/20220228201006.1484903-1-robh@xxxxxxxxxx/ Rob Herring (2): dt-bindings: kbuild: Pass DT_SCHEMA_FILES to dt-validate dt-bindings: kbuild: Use DTB files for validation Documentation/devicetree/bindings/Makefile | 35 ++++--------------- .../devicetree/bindings/writing-schema.rst | 12 ------- scripts/Makefile.lib | 25 +++++-------- scripts/dtc/Makefile | 13 ------- scripts/dtc/update-dtc-source.sh | 2 +- 5 files changed, 16 insertions(+), 71 deletions(-) -- 2.32.0
