    1 Sigma Designs Tango4 NAND Flash Controller (NFC)
    2 
    3 Required properties:
    4 
    5 - compatible: "sigma,smp8758-nand"
    6 - reg: address/size of nfc_reg, nfc_mem, and pbus_reg
    7 - dmas: reference to the DMA channel used by the controller
    8 - dma-names: "rxtx"
    9 - clocks: reference to the system clock
   10 - #address-cells: <1>
   11 - #size-cells: <0>
   12 
   13 Children nodes represent the available NAND chips.
   14 See Documentation/devicetree/bindings/mtd/nand-controller.yaml for generic bindings.
   15 
   16 Example:
   17 
   18         nandc: nand-controller@2c000 {
   19                 compatible = "sigma,smp8758-nand";
   20                 reg = <0x2c000 0x30>, <0x2d000 0x800>, <0x20000 0x1000>;
   21                 dmas = <&dma0 3>;
   22                 dma-names = "rxtx";
   23                 clocks = <&clkgen SYS_CLK>;
   24                 #address-cells = <1>;
   25                 #size-cells = <0>;
   26

   30                         nand-ecc-step-size = <1024>;
   31                 };
   32
