I have some serious doubts again about this whole ------ up string parsing pile of ---- called device tree. Do we really need to sprinkle more of_* hacks to the irq subsystem? There's nothing wrong with with the irq subsystem. Platform bus is just calling the irq subsystem at the wrong time with uninitialized data. It seems that we're again papering over the fact that there's nothing coordinating the setting up of various resources with device tree. That seems to be the repeating never ending pattern as we've already seen with GPIOs, pinctrl, and IRQchips. We end up adding all kinds of cross subsystem calls that were never needed earlier.
