Well the problem I'm seeing is these nasty warnings.
BTW, I think the issue you're talking about regarding platform_get_irq()
got fixed by 4a43d686fe33 (of/irq: Pass trigger type in IRQ resource flags).

Yes I agree it's rather invasive, but we also do have things pretty
badly broken in the kernel for device tree based booting. And it seems
that nobody has a smaller patch that would fix it.
