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". > >> +- reg : chip select value >> +- label : optional user friendly label >> + >> +Example: >> + >> +qspi: spi@a0001000 { >> + compatible = "altr,asmi_parallel2"; >> + reg = <0xa0001000 0x10>; >> + >> + flash@0 { > > This should have a compatible. > >> + reg = <0>; >> + label = "FPGA Image"; >> + }; Since I have no way to test multiple flash chips, it might be simpler to not specify any subnodes. >> +}; >> -- >> 2.7.4 >> > -- To unsubscribe from this list: send the line "unsubscribe linux-fpga" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
