Please make any YAML conversion patches the last patches in a series -
there's frequently a backlog in reviewing them so having the DT binding
patches first blocks any progress on everything else in the series.

OK, I mistake to lost " dt-bindings: spi: Convert spi-slave-mt27xx to
json-schema" on V3 series, I'll send it again, thanks
