Lattice MachXO2 Slave SPI FPGA Manager
Lattice MachXO2 FPGAs support a method of loading the bitstream over
'slave SPI' interface.
See 'MachXO2ProgrammingandConfigurationUsageGuide.pdf' on www.latticesemi.com
Required properties:
- compatible: should contain "lattice,machxo2-slave-spi"
- reg: spi chip select of the FPGA
Example for full FPGA configuration:
fpga-region0 {
compatible = "fpga-region";
fpga-mgr = <&fpga_mgr_spi>;
#address-cells = <0x1>;
#size-cells = <0x1>;
};
spi1: spi@2000 {
...
fpga_mgr_spi: fpga-mgr@0 {
compatible = "lattice,machxo2-slave-spi";
spi-max-frequency = <8000000>;
reg = <0>;
};
};
