From e400edb141d74aa2f04d0071aadb47fdb8f7ae55 Mon Sep 17 00:00:00 2001 From: Rob Herring Date: Thu, 12 Sep 2019 15:18:20 +0100 Subject: [PATCH] checkpatch: Warn if DT bindings are not in schema format DT bindings are moving to using a json-schema based schema format instead of freeform text. Add a checkpatch.pl check to encourage using the schema for new bindings. It's not yet a requirement, but is progressively being required by some maintainers.
