"cyclonespi" does not strike me as the best node name.

I am guessing this is a sub-node of a SPI controller node, so no need to
repeat "spi", and Cyclone seems more or less implied by "altr,fpga-".

True.

Note that the example in the bindings doc uses "evi-fpga-spi". Nodes
don't need to be (shouldn't be?) prefixed with the board. Note that
bindings examples tend to get copied a lot.

Any reason not to just use "fpga at 0" in both places for simplicity?

Sure. fpga: fpga at 0 is probably better.

Note that I was only commenting on the node name, the latter part.

I'm not aware of any rules for the label, so that could remain unchanged
or adopt cyclone_spi from the old node name or whatever is unique and
syntactically valid.

Too late! Patches posted.
Oh, well, I'm not changing it back.

I'll change it in both the dts and the binding doc.

Thanks. Maybe double-check if there's any conventions Xilinx/Lattice DTs
are using.

Of the conventions I found, fpga seemed the most "hardware descriptive"
for a plain FPGA.
The other one several binding doc examples are using is "fpga-mgr".

Cheers,
Andreas
