-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>;
-		};
-	};
