+Freescale's NAND flash controller (NFC)
+
+This variant of the Freescale NAND flash controller (NFC) is on Vybrid (vf610),
+MPC5125, MCF54418 and Kinetis K70.
+
+Required properties:
+- compatible: "fsl,vf610-nfc"
+- reg: Address range of the mtd chip
+- interrupts: Should contain the STMMAC interrupts
+- nand-bus-width: see nand.txt
+- nand-ecc-mode: see nand.txt
+- nand-on-flash-bbt: see nand.txt
+- clock-frequency : Optional clock rate to NFC in Hz
+- #address-cells, #size-cells : Must be present if the device has sub-nodes
+  representing partitions.
+
+Required properties for hardware ECC:
+- nand-ecc-strength: supported strengths are 24 and 32 (see nand.txt)
+- nand-ecc-step-size: step size equals page size, currently only 2k pages are
+  supported
+
+Example:
+
+	nfc: nand@400e0000 {
+		compatible = "fsl,vf610-nfc";
+		#address-cells = <1>;
+		#size-cells = <1>;
+		reg = <0x400e0000 0x4000>;
+		interrupts = <GIC_SPI 83 IRQ_TYPE_LEVEL_HIGH>;
+		clocks = <&clks VF610_CLK_NFC>;
+		clock-names = "nfc";
+		clock-frequency = <33000000>;
+		nand-bus-width = <8>;
+		nand-ecc-mode = "hw";
+		nand-on-flash-bbt;
+		nand-ecc-strength = <32>;
+		nand-ecc-step-size = <2048>;
+	};
