  Amlogic Meson SPI controllers
  
  * SPIFC (SPI Flash Controller)
  
  The Meson SPIFC is a controller optimized for communication with SPI
  NOR memories, without DMA support and a 64-byte unified transmit /
  receive buffer.
  
  Required properties:
   - compatible: should be "amlogic,meson6-spifc"
   - reg: physical base address and length of the controller registers
   - clocks: phandle of the input clock for the baud rate generator
   - #address-cells: should be 1
   - #size-cells: should be 0
  
  	spi@c1108c80 {
  		compatible = "amlogic,meson6-spifc";
  		reg = <0xc1108c80 0x80>;
  		clocks = <&clk81>;
  		#address-cells = <1>;
  		#size-cells = <0>;
  	};
