Your only suggestion is that hardware that is not driven by kernel is
described to the kernel. I have written in great detail why this does
not make sense.

So to me it seems that you reject out of hand any suggestion that
is not the one solution you are demanding. You have not raised any
concrete reason against the proposed solution other than it does not
describe the hardware. The hardware cannot be described for practical
usability reasons.

Is there any solution that fits the driver model and allows using spidev with
arbitrary device without describing said device in devicetree?

Thanks
