   1 Device tree bindings for GPMC connected OneNANDs
   2
   3 GPMC connected OneNAND (found on OMAP boards) are represented as child nodes of
   4 the GPMC controller with a name of "onenand".
   5
   6 All timing relevant properties as well as generic gpmc child properties are
   7 explained in a separate documents - please refer to
   8 Documentation/devicetree/bindings/bus/ti-gpmc.txt

  10 Required properties:
  11
  12  - reg:                 The CS line the peripheral is connected to
  13  - gpmc,device-width    Width of the ONENAND device connected to the GPMC
  14                         in bytes. Must be 1 or 2.

  16 Optional properties:
  17
  18  - dma-channel:         DMA Channel index
  19
  20 For inline partition table parsing (optional):
  21
  22  - #address-cells: should be set to 1
  23  - #size-cells: should be set to 1

  25 Example for an OMAP3430 board:
  26
  27         gpmc: gpmc@6e000000 {
  28                 compatible = "ti,omap3430-gpmc";
  29                 ti,hwmods = "gpmc";
  30                 reg = <0x6e000000 0x1000000>;
  31                 interrupts = <20>;
  32                 gpmc,num-cs = <8>;
  33                 gpmc,num-waitpins = <4>;
  34                 #address-cells = <2>;
  35                 #size-cells = <1>;
  36
  37                 onenand@0 {
  38                         reg = <0 0 0>; /* CS0, offset 0 */
  39                         gpmc,device-width = <2>;
  40
  41                         #address-cells = <1>;
  42                         #size-cells = <1>;
  43
  44                         /* partitions go here */
  45                 };
  46         };
