| Allwinner NAND Flash Controller (NFC) |
| |
| Required properties: |
| - compatible : "allwinner,sun4i-a10-nand". |
| - reg : shall contain registers location and length for data and reg. |
| - interrupts : shall define the nand controller interrupt. |
| - #address-cells: shall be set to 1. Encode the nand CS. |
| - #size-cells : shall be set to 0. |
| - clocks : shall reference nand controller clocks. |
| - clock-names : nand controller internal clock names. Shall contain : |
| * "ahb" : AHB gating clock |
| * "mod" : nand controller clock |
| |
| Optional children nodes: |
| Children nodes represent the available nand chips. |
| |
| Optional properties: |
| - allwinner,rb : shall contain the native Ready/Busy ids. |
| or |
| - rb-gpios : shall contain the gpios used as R/B pins. |
| - nand-ecc-mode : one of the supported ECC modes ("hw", "hw_syndrome", "soft", |
| "soft_bch" or "none") |
| |
| see Documentation/devicetree/bindings/mtd/nand.txt for generic bindings. |

| Examples: |
| nfc: nand@01c03000 { |
| compatible = "allwinner,sun4i-a10-nand"; |
| reg = <0x01c03000 0x1000>; |
| interrupts = <0 37 1>; |
| clocks = <&ahb_gates 13>, <&nand_clk>; |
| clock-names = "ahb", "mod"; |
| #address-cells = <1>; |
| #size-cells = <0>; |
| pinctrl-names = "default"; |
| pinctrl-0 = <&nand_pins_a &nand_cs0_pins_a &nand_rb0_pins_a>; |
| status = "okay"; |
| |
| nand@0 { |
| reg = <0>; |
| allwinner,rb = <0>; |
| nand-ecc-mode = "soft_bch"; |
