1	* Freescale General-Purpose Media Interface (GPMI)
2	
3	The GPMI nand controller provides an interface to control the
4	NAND flash chips. We support only one NAND chip now.
5	
6	Required properties:
7	  - compatible : should be "fsl,<chip>-gpmi-nand"
8	  - reg : should contain registers location and length for gpmi and bch.
9	  - reg-names: Should contain the reg names "gpmi-nand" and "bch"
10	  - interrupts : BCH interrupt number.
11	  - interrupt-names : Should be "bch".
12	  - dmas: DMA specifier, consisting of a phandle to DMA controller node
13	    and GPMI DMA channel ID.
14	    Refer to dma.txt and fsl-mxs-dma.txt for details.
15	  - dma-names: Must be "rx-tx".
16	
17	Optional properties:
18	  - nand-on-flash-bbt: boolean to enable on flash bbt option if not
19	                       present false
20	
21	The device tree may optionally contain sub-nodes describing partitions of the
22	address space. See partition.txt for more detail.
23	
24	Examples:
25	
26	gpmi-nand@8000c000 {
27		compatible = "fsl,imx28-gpmi-nand";
28		#address-cells = <1>;
29		#size-cells = <1>;
30		reg = <0x8000c000 2000>, <0x8000a000 2000>;
31		reg-names = "gpmi-nand", "bch";
32		interrupts = <41>;
33		interrupt-names = "bch";
34		dmas = <&dma_apbh 4>;
35		dma-names = "rx-tx";
36	
37		partition@0 {
38		...
39		};
40	};
