Hi Rob,

Thanks for the steps. I seeing minimum version error, though the dtschema is latest.

$ make dt_binding_check
sort: -:2: disorder: 0
ERROR: dtschema minimum version is v2021.2.1
Documentation/devicetree/bindings/Makefile:12: recipe for target 'check_dtschema_version' failed
make[1]: *** [check_dtschema_version] Error 1
Makefile:1418: recipe for target 'dt_binding_check' failed
make: *** [dt_binding_check] Error 2

$ pip3 show dtschema
Name: dtschema
Version: 2021.7
Summary: DeviceTree validation schema and tools
