| 2 | |
| 3 | Lattice MachXO2 FPGAs support a method of loading the bitstream over |
| 4 | 'slave SPI' interface. |
| 5 | |
| 6 | See 'MachXO2ProgrammingandConfigurationUsageGuide.pdf' on www.latticesemi.com |
| 7 | |
| 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 | }; |
