+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
+
+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 */
+
+ #address-cells = <1>;
+ #size-cells = <1>;
+
+ /* partitions go here */
+ };
+ };
