* Samsung S3C2410 and compatible NAND flash controller
Required properties:
- compatible : The possible values are:
"samsung,s3c2410-nand"
"samsung,s3c2412-nand"
"samsung,s3c2440-nand"
- reg : register's location and length.
- #address-cells, #size-cells : see nand.txt
- clocks : phandle to the nand controller clock
- clock-names : must contain "nand"
Optional child nodes:
Child nodes representing the available nand chips.
Optional child properties:
- nand-ecc-mode : see nand.txt
- nand-on-flash-bbt : see nand.txt
Each child device node may optionally contain a 'partitions' sub-node,
which further contains sub-nodes describing the flash partition mapping.
See partition.txt for more detail.
Example:
nand-controller@4e000000 {
compatible = "samsung,s3c2440-nand";
reg = <0x4e000000 0x40>;
#address-cells = <1>;
#size-cells = <0>;
clocks = <&clocks HCLK_NAND>;
clock-names = "nand";
nand {
nand-ecc-mode = "soft";
nand-on-flash-bbt;
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
partition@0 {
label = "u-boot";
reg = <0 0x040000>;
};
partition@40000 {
label = "kernel";
reg = <0x040000 0x500000>;
};
};
};
};
