| 2 | ------------------------------------------------- |
| 3 | |
| 4 | Required properties: |
| 5 | - compatible: should be "mxic,multi-itfc-v009-nand-controller" |
| 6 | - reg: should contain 1 entry for the registers |
| 7 | - #address-cells: should be set to 1 |
| 8 | - #size-cells: should be set to 0 |
| 9 | - interrupts: interrupt line connected to this raw NAND controller |
| 10 | - clock-names: should contain "ps", "send" and "send_dly" |
| 11 | - clocks: should contain 3 phandles for the "ps", "send" and |
| 12 | "send_dly" clocks |
| 13 | |
| 14 | Children nodes: |
| 15 | - children nodes represent the available NAND chips. |
| 16 | |
| 17 | See Documentation/devicetree/bindings/mtd/nand-controller.yaml |
| 18 | for more details on generic bindings. |

| 20 | Example: |
| 21 | |
| 22 | nand: nand-controller@43c30000 { |
| 23 | compatible = "mxic,multi-itfc-v009-nand-controller"; |
| 24 | reg = <0x43c30000 0x10000>; |
| 25 | #address-cells = <1>; |
| 26 | #size-cells = <0>; |
| 27 | interrupts = <GIC_SPI 0x1d IRQ_TYPE_EDGE_RISING>; |
| 28 | clocks = <&clkwizard 0>, <&clkwizard 1>, <&clkc 15>; |
| 29 | clock-names = "send", "send_dly", "ps"; |
| 30 | |
| 31 | nand@0 { |
| 32 | reg = <0>; |
| 33 | nand-ecc-mode = "soft"; |
| 34 | nand-ecc-algo = "bch"; |
| 35 | }; |
