The series introduces a new platform. The patches are touching
different susystems managed by different maintainers.

Usually, the changes are per subsystem, except when they are
interdependant.

Here you can choose to merge all the patches through the mips tree or
let the different maintainers to pick the changes related to the
subsystems they handle. You should clarify that in the cover
letter. If you choose the first alternative, then before merging the
changes, all maintainer should have blessed the patches with their
acked-by.
