-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 properties:
-- dmas : shall reference DMA channel associated to the NAND controller.
-- dma-names : shall be "rxtx".
-
-Optional children nodes:
-Children nodes represent the available nand chips.
-
-Optional properties:
-- reset : phandle + reset specifier pair
-- reset-names : must contain "ahb"
-- allwinner,rb : shall contain the native Ready/Busy ids.
-- nand-ecc-mode : one of the supported ECC modes ("hw", "soft", "soft_bch" or
- "none")
-
-see Documentation/devicetree/bindings/mtd/nand.txt for generic bindings.

-Examples:
-nfc: nand@1c03000 {
- compatible = "allwinner,sun4i-a10-nand";
- reg = <0x01c03000 0x1000>;
- interrupts = <0 37 1>;

- #address-cells = <1>;
- #size-cells = <0>;
- pinctrl-names = "default";
- pinctrl-0 = <&nand_pins_a &nand_cs0_pins_a &nand_rb0_pins_a>;
