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/memory-controllers/omap-gpmc.txt
9
10Required properties:
11
12 - compatible: "ti,omap2-onenand"
13 - reg: The CS line the peripheral is connected to
14 - gpmc,device-width: Width of the ONENAND device connected to the GPMC
15 in bytes. Must be 1 or 2.
16
17Optional properties:
18
19 - int-gpios: GPIO specifier for the INT pin.
20
21For inline partition table parsing (optional):
22
23 - #address-cells: should be set to 1
24 - #size-cells: should be set to 1
25
26Example for an OMAP3430 board:
27
28 gpmc: gpmc@6e000000 {
29 compatible = "ti,omap3430-gpmc";
30 ti,hwmods = "gpmc";
31 reg = <0x6e000000 0x1000000>;
32 interrupts = <20>;
33 gpmc,num-cs = <8>;
34 gpmc,num-waitpins = <4>;
35 #address-cells = <2>;
36 #size-cells = <1>;
37
38 onenand@0 {
39 compatible = "ti,omap2-onenand";
40 reg = <0 0 0>; /* CS0, offset 0 */
41 gpmc,device-width = <2>;
42
43 #address-cells = <1>;
44 #size-cells = <1>;
45
46 /* partitions go here */
47 };
48 };
