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:
|
|
|
|
- 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 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 {
|
|
reg = <0 0 0>; /* CS0, offset 0 */
|
|
gpmc,device-width = <2>;
|
|
|
|
#address-cells = <1>;
|
|
#size-cells = <1>;
|
|
|
|
/* partitions go here */
|
|
};
|
|
};
