1Sigma Designs Tango4 NAND Flash Controller (NFC) 2 3Required 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 13Children nodes represent the available NAND chips. 14See Documentation/devicetree/bindings/mtd/nand-controller.yaml for generic bindings. 15 16Example: 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 27 nand@0 { 28 reg = <0>; /* CS0 */ 29 nand-ecc-strength = <14>; 30 nand-ecc-step-size = <1024>; 31 }; 32 33 nand@1 { 34 reg = <1>; /* CS1 */ 35 nand-ecc-strength = <14>; 36 nand-ecc-step-size = <1024>; 37 }; 38 }; 39
