But this is not a general purpose SPI controller?

This should have a compatible.

The component is a general pupose SPI controller, but this driver
expects a spi-nor device to be connected to it.  As such I wonder if the
compatible string should be "altr,asmi-parallel2-spi-nor".

Since I have no way to test multiple flash chips, it might
be simpler to not specify any subnodes.
