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/bus/ti-gpmc.txt
Required properties:
- 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:
- dma-channel: DMA Channel index
For inline partiton 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 {
reg = <0 0 0>; /* CS0, offset 0 */
gpmc,device-width = <2>;
#address-cells = <1>;
#size-cells = <1>;
/* partitions go here */
};
};
