1 Lattice MachXO2 Slave SPI FPGA Manager
2
3 Lattice MachXO2 FPGAs support a method of loading the bitstream over
4 'slave SPI' interface.

8 Required properties:
9 - compatible: should contain "lattice,machxo2-slave-spi"
10 - reg: spi chip select of the FPGA
11
12 Example for full FPGA configuration:
13
14 fpga-region0 {
15 compatible = "fpga-region";
16 fpga-mgr = <&fpga_mgr_spi>;
17 #address-cells = <0x1>;
18 #size-cells = <0x1>;
19 };
20
21 spi1: spi@2000 {
22 ...
23
24 fpga_mgr_spi: fpga-mgr@0 {
25 compatible = "lattice,machxo2-slave-spi";
26 spi-max-frequency = <8000000>;
27 reg = <0>;
28 };
29 };
