Yes and no warnings or errors with these checks 

make ARCH=arm64 dtbs_check
make DT_CHECKER_FLAGS=-m dt_binding_check 

but I did find a couple relevant packages have been updated

dtschema Version: 2023.1  ==> 2023.4
yamllint Version: 1.26.3  ==> 1.30.0

and then running again I get below 

$ make ARCH=arm64 dtbs_check 
...

I'll fix this in the next spin.
