No, this is broken - nothing should ever bind to spidev as spidev. The
fact that we have a binding document at all is a bug.

And how do you get spidev if nothing binds to it?

When you boot without the binding no device is created.

Describe your actual hardware in the DT then add the relevant device ID
to spidev.

I think there is actual a use for just binding spidev as spidev,
think e.g. the spi pins on the raspberry pi.

How do you deal we suggest with such a situation ?

Hans
