* 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 {
...
};
};
