* 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/spi_flash_ids.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>;
};
