Oh, and this patch should add documentation to
Documentation/devicetree/bindings/spi specifying exactly what device
this compatible string represents and what properties are expected to
be in the node (if any) beyond the standard reg, interrupts, etc.  It
doesn't need to be huge and detailed, but it at least needs to show
that the string is in use.  This comment goes for the other patches
that add bindings too.
