PXA3xx NAND DT bindings
Required properties:
- compatible: Should be set to one of the following:
marvell,pxa3xx-nand
marvell,armada370-nand
marvell,armada-8k-nand
- reg: The register base for the controller
- interrupts: The interrupt to map
- #address-cells: Set to <1> if the node includes partitions
- marvell,system-controller: Set to retrieve the syscon node that handles
NAND controller related registers (only required
with marvell,armada-8k-nand compatible).
Optional properties:
- dmas: dma data channel, see dma.txt binding doc
- marvell,nand-enable-arbiter: Set to enable the bus arbiter
- marvell,nand-keep-config: Set to keep the NAND controller config as set
by the bootloader
- num-cs: Number of chipselect lines to use
- nand-on-flash-bbt: boolean to enable on flash bbt option if
not present false
- nand-ecc-strength: number of bits to correct per ECC step
- nand-ecc-step-size: number of data bytes covered by a single ECC step
The following ECC strength and step size are currently supported:
- nand-ecc-strength = <1>, nand-ecc-step-size = <512>
- nand-ecc-strength = <4>, nand-ecc-step-size = <512>
- nand-ecc-strength = <8>, nand-ecc-step-size = <512>
Example:
nand0: nand@43100000 {
compatible = "marvell,pxa3xx-nand";
reg = <0x43100000 90>;
interrupts = <45>;
dmas = <&pdma 97 0>;
dma-names = "data";
#address-cells = <1>;
marvell,nand-enable-arbiter;
marvell,nand-keep-config;
num-cs = <1>;
/* partitions (optional) */
};
