 wishing that to happen does not make it happen, especially when SoC
vendors do not communicate with upstream and repeatedly copy rather
than consolidate.

 also, SoC vendors have nothing to do with hardware device manufacturers.

 so it still does not resolve the issue of having to customise a
linux-kernel-plus-a-devicetree-file to a device.

 previous situation: ODM uniquely customises a linux kernel to a device.

 future situation: ODM uniquely customises a linux kernel plus a
devicetree file to a device.

 so the linux kernel has pushed the problem away and out of their
responsibility?  so what.  actually creating a real hardware device is
still just as much a nightmare.
