+* Freescale General-Purpose Media Interface (GPMI)
+
+The GPMI nand controller provides an interface to control the
+NAND flash chips. We support only one NAND chip now.
+
+Required properties:
+  - compatible : should be "fsl,<chip>-gpmi-nand"
+  - reg : should contain registers location and length for gpmi and bch.
+  - reg-names: Should contain the reg names "gpmi-nand" and "bch"
+  - interrupts : The first is the DMA interrupt number for GPMI.
+                 The second is the BCH interrupt number.
+  - interrupt-names : The interrupt names "gpmi-dma", "bch";
+  - fsl,gpmi-dma-channel : Should contain the dma channel it uses.
+
+The device tree may optionally contain sub-nodes describing partitions of the
+address space. See partition.txt for more detail.
+
+Examples:
+
+gpmi-nand@8000c000 {
+	compatible = "fsl,imx28-gpmi-nand";
+	#address-cells = <1>;
+	#size-cells = <1>;
+	reg = <0x8000c000 2000>, <0x8000a000 2000>;
+	reg-names = "gpmi-nand", "bch";
+	interrupts = <88>, <41>;
+	interrupt-names = "gpmi-dma", "bch";
+	fsl,gpmi-dma-channel = <4>;
+
+	partition@0 {
+	...
+	};
+};
