That situation is different, when a new facility is added and someone
has gone through the work of adding support for all architectures (or
nearly all of them), you want them to be merged in a way that limits
merge conflicts with other architecture changes.

Here you are fixing warnings, and each file you touch can clearly be
independently change from other files in the series without causing
merge conflicts. You are however creating the potential for merge
conflicts with other changes that the various SoC maintainers have
queued up.

Maybe Rob can queue them through his device tree repository, with the
ack of the various SoC maintainers...
