Add support for Altera V FPGA connected to an spi port
Did you mean "Altera Cyclone V"?

"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-". 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?
