   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 : The first is the DMA interrupt number for GPMI.
  11                  The second is the BCH interrupt number.
  12   - interrupt-names : The interrupt names "gpmi-dma", "bch";
  13   - fsl,gpmi-dma-channel : Should contain the dma channel it uses.
  14
  15 Optional properties:
  16   - nand-on-flash-bbt: boolean to enable on flash bbt option if not
  17                        present false
  18
  19 The device tree may optionally contain sub-nodes describing partitions of the
  20 address space. See partition.txt for more detail.

  22 Examples:
  23
  24 gpmi-nand@8000c000 {
  25         compatible = "fsl,imx28-gpmi-nand";
  26         #address-cells = <1>;
  27         #size-cells = <1>;
  28         reg = <0x8000c000 2000>, <0x8000a000 2000>;
  29         reg-names = "gpmi-nand", "bch";
  30         interrupts = <88>, <41>;
  31         interrupt-names = "gpmi-dma", "bch";
  32         fsl,gpmi-dma-channel = <4>;

  34         partition@0 {
  35         ...
  36         };
  37 };
