From 4f0e3a57d6eb727c54249542c509e0b7aa122465 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Thu, 6 Sep 2018 13:26:07 -0500 Subject: kbuild: Add support for DT binding schema checks This adds the build infrastructure for checking DT binding schema documents and validating dts files using the binding schema. Check DT binding schema documents: make dt_binding_check Build dts files and check using DT binding schema: make dtbs_check Optionally, DT_SCHEMA_FILES can be passed in with a schema file(s) to use for validation. This makes it easier to find and fix errors generated by a specific schema. Currently, the validation targets are separate from a normal build to avoid a hard dependency on the external DT schema project and because there are lots of warnings generated.
