Properties defining the NPCX Quad-SPI peripheral of Flash Interface Unit (FIU).
|
|
A npcx quad-spi dt node would typically looks like:
|
|
|
|
&qspi_fiu0 {
|
|
status = "okay";
|
|
|
|
int_flash: w25q400@0 {
|
|
status = "okay";
|
|
reg = <0>;
|
|
...
|
|
};
|
|
|
|
ext_flash: w25q256@1 {
|
|
status = "okay";
|
|
reg = <1>;
|
|
...
|
|
};
|
|
};
|
|
|
|
`int_flash` and `ext_flash` are the devices accessed by this peripheral.
