Looks as if it was sitting too long in the queue and linux-next has changed
the basis in the meantime, while v5.3 has not yet.

Documentation/devicetree/bindings/spi/spi-bus.txt -> spi-controller.yaml

So it should still apply for v5.3.1 and earlier and we need both versions.
One for stable and one for linux-next. I don't know how to handle such cases.
