Ah, I think I suggested something garbage, because I misread the diff,
as my quoted mail evidences. I was really trying to suggest putting
spi-cpha: true
spi-cpol: true
in trivial-devices.yaml, but I didn't notice that the patch was to
spi-peripheral-props rather than trivial-devices. These properties are
defined (for reasons I don't quite understand) in spi-controller.yaml
and applied to children of the controller node by that binding and I
wanted to avoid the redefinition.
