There are separate patches that touch the different subsystems, but
they're all scattered throughout the one series, rather than having e.g.:

* a series for the PCI tree
* a series for the ARM core tree
* a series for the OF/DT tree
* a series for the Tegra tree, which indicates it depends on all of those.

I'm wondering if the reason you haven't seen much discussion/Acks from
the maintainers of the non-Tegra trees is because this is a big scary
series that touches a lot of stuff, and it's not necessarily clear for
people unfamiliar with it why they're being CCd on it.
