The time to run dt_binding_check and dtbs_check has gotten significantly slower as the number of schemas has increased. There's 2 main factors causing validation time on each file to be slow. The first is python start-up time. This is a common problem for python without much of a solution other than minimizing module imports. Eliminating some imports was possible for dt-extract-example, but not the other tools. Validating multiple files in a single call is the simplest solution. The downside of processing multiple files in one call is losing make dependency handling. This is not too important for dt-doc-validate as the validation time is <10 sec. The 2nd factor is processed-schema*.yaml is now ~2MB and around 2 sec to parse (which is done for every .dts and example). Switching processed-schema*.yaml to JSON is much faster to parse The overall result of these changes is a 2x improvement to dtbs_check and a 4-5x improvement to dt_binding_check.
