-Device tree bindings for GPMC connected OneNANDs
-
-GPMC connected OneNAND (found on OMAP boards) are represented as child nodes of
-the GPMC controller with a name of "onenand".
-
-All timing relevant properties as well as generic gpmc child properties are
-explained in a separate documents - please refer to
-Documentation/devicetree/bindings/memory-controllers/omap-gpmc.txt
-
-Required properties:
-
- - compatible: "ti,omap2-onenand"
- - reg: The CS line the peripheral is connected to
- - gpmc,device-width: Width of the ONENAND device connected to the GPMC
- in bytes. Must be 1 or 2.
-
-Optional properties:
-
- - int-gpios: GPIO specifier for the INT pin.
-
-For inline partition table parsing (optional):
-
- - #address-cells: should be set to 1
- - #size-cells: should be set to 1
-
-Example for an OMAP3430 board:
-
- gpmc: gpmc@6e000000 {
- compatible = "ti,omap3430-gpmc";
- ti,hwmods = "gpmc";
- reg = <0x6e000000 0x1000000>;
- interrupts = <20>;
- gpmc,num-cs = <8>;
- gpmc,num-waitpins = <4>;
- #address-cells = <2>;
- #size-cells = <1>;
-
- onenand@0 {
- compatible = "ti,omap2-onenand";
- reg = <0 0 0>; /* CS0, offset 0 */
- gpmc,device-width = <2>;
-
- #address-cells = <1>;
- #size-cells = <1>;
-
- /* partitions go here */
- };
- };
