   2
   3 Required properties:
   4 - compatible: Must be "img,spfi".
   5 - reg: Must contain the base address and length of the SPFI registers.
   6 - interrupts: Must contain the SPFI interrupt.
   7 - clocks: Must contain an entry for each entry in clock-names.
   8   See ../clock/clock-bindings.txt for details.
   9 - clock-names: Must include the following entries:
  10   - spfi: SPI operating clock
  11   - sys: SPI system interface clock
  12 - dmas: Must contain an entry for each entry in dma-names.
  13   See ../dma/dma.txt for details.
  14 - dma-names: Must include the following entries:
  15   - rx
  16   - tx
  17 - #address-cells: Must be 1.
  18 - #size-cells: Must be 0.
  19
  20 Optional properties:
  21 - img,supports-quad-mode: Should be set if the interface supports quad mode
  22   SPI transfers.

  28         reg = <0x18100f00 0x100>;
  29         interrupts = <GIC_SHARED 22 IRQ_TYPE_LEVEL_HIGH>;
  30         clocks = <&spi_clk>, <&system_clk>;
  31         clock-names = "spfi", "sys";
  32         dmas = <&mdc 9 0xffffffff 0>, <&mdc 10 0xffffffff 0>;
  33         dma-names = "rx", "tx";
