Hi Masahiro Thanks for the nice improvements to the dt infrastructure. Stealing a thread here.. > It is also possible to run checks with a single schema file by setting the > ``DT_SCHEMA_FILES`` variable to a specific schema file. Would it be simple to enable the use of dirs for DT_SCHEMA_FILES? So I for example could do: make dt_bindings_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/display/panel/ I did a very quick look add it but failed to dechiper all the makefile logic. It is a corner case when one wants to check a full dir, so unless it is very simple the current logic should not be complicated by this (if you take the bait and look at it). Sam
