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.
