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

  10Required 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.
  15
  16Optional properties:
  17
  18 - dma-channel:         DMA Channel index
  19
  20For inline partiton table parsing (optional):
  21
  22 - #address-cells: should be set to 1
  23 - #size-cells: should be set to 1
  24
  25Example 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        };
