Note

An implementation of a driver matching this compatible is available in drivers/flash/flash_npcx_fiu_qspi.c.

Description

These nodes are “qspi” bus nodes.

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.
