kbuild: Enable DT undocumented compatible checks
dt-validate has an option to warn on any compatible strings which don't match any schema. The option has recently been improved to fix false positives, so let's enable the option. This is useful for tracking compatibles which are undocumented or not yet converted to DT schema. Previously, the only check of undocumented compatible strings has been an imperfect check. The option is enabled by default for 'dtbs_check'. This will add more warnings, but some platforms are down to only a handful of these warnings (good job!). There's about 100 cases in the binding examples, so the option is disabled until these are fixed. In the meantime, they can be checked with: make DT_CHECKER_FLAGS=-m dt_binding_check Cc: Maxime Ripard <> Cc: Masahiro Yamada <> Cc: Michal Marek <> Cc: Signed-off-by: Rob Herring <> Link:
