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.
