Yep, I am aware of that. I am still trying to recover after recent
gpio-ranges fiasco, also still working on fixing non-exported firmware
clocks, which break HDMI output on some of the devices.

Well, 260+ overlays for free is not insignificant benefit. Beside few
breakages from time to time using downstream device tree works fine.
