TCSR is not compatible with syscon, because there is no such device as
syscon. That's Linuxism. One device cannot be compatible with non-device
Linuxism.

Few other commits also are not helping - you keep repeating the binding,
that device is compatible with some other "compatible". But we
never asked for it. We asked to describe this hardware or say something
not visible in the diff - why you are using one or other fallback.

Best regards,
Krzysztof

Ok, I will just drop it.
