* MTD SPI driver for serial flash chips
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- #address-cells, #size-cells : Must be present if the device has sub-nodes
|
||
|
|
representing partitions.
|
||
|
|
- compatible : Should be the manufacturer and the name of the chip. Bear in
|
||
|
|
mind that the DT binding is not U-Boot-only, but in case of
|
||
|
|
U-Boot, see spi_flash_params_table table in
|
||
|
|
drivers/mtd/spi/sf_params.c for the list of supported chips.
|
||
|
|
- reg : Chip-Select number
|
||
|
|
- spi-max-frequency : Maximum frequency of the SPI bus the chip can operate at
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- memory-map : Address and size of the flash, if memory mapped. This may
|
||
|
|
apply to Intel chipsets, which tend to memory-map flash.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
flash: m25p80@0 {
|
||
|
|
#address-cells = <1>;
|
||
|
|
#size-cells = <1>;
|
||
|
|
compatible = "spansion,m25p80";
|
||
|
|
reg = <0>;
|
||
|
|
spi-max-frequency = <40000000>;
|
||
|
|
};
