* Oxford Semiconductor OXNAS NAND Controller
|
|
|
|
Please refer to nand.txt for generic information regarding MTD NAND bindings.
|
|
|
|
Required properties:
|
|
- compatible: "oxsemi,ox820-nand"
|
|
- reg: Base address and length for NAND mapped memory.
|
|
|
|
Optional Properties:
|
|
- clocks: phandle to the NAND gate clock if needed.
|
|
- resets: phandle to the NAND reset control if needed.
|
|
|
|
Example:
|
|
|
|
nandc: nand-controller@41000000 {
|
|
compatible = "oxsemi,ox820-nand";
|
|
reg = <0x41000000 0x100000>;
|
|
clocks = <&stdclk CLK_820_NAND>;
|
|
resets = <&reset RESET_NAND>;
