From dee9c0b57594834fdd65dc476ea2890592bcf35c Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Fri, 26 Jun 2020 02:04:33 +0900 Subject: [PATCH] dt-bindings: copy process-schema-examples.yaml to process-schema.yaml There are two processed schema files: - processed-schema-examples.yaml Used for 'make dt_binding_check'. This is always a full schema. - processed-schema.yaml Used for 'make dtbs_check'. This may be a full schema, or a smaller subset if DT_SCHEMA_FILES is given by a user. If DT_SCHEMA_FILES is not specified, they are the same. You can copy the former to the latter instead of running dt-mk-schema twice. This saves the cpu time a lot when you do 'make dt_binding_check dtbs_check' because building the full schema takes a couple of seconds. If DT_SCHEMA_FILES is specified, processed-schema.yaml is generated based on the specified yaml files.
