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
9
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 partition 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	};
