How to Configure DTS and Struct for SPI Controller Driver with Child Nodes in Zephyr?

that way We can write the dts like below soc.dtsi

/soc {
    spi0: spi@48030000 {
        compatible = "ti,omap-spi";
        reg = <0x48030000 0x1000>;
        interrupts = <41>;
        spi-max-frequency = <48000000>;
        status = "disabled";
    };
};

board.dts

    &spi0 {
        status = "okay";
    };
};

sensor.overlay

&spi0 {
    sensor@0 {
        compatible = "generic,sensor";
        reg = <0>;
        frequency = <12000000>;
        ti,cs-delay = <10>;
        label = "SENSOR_0";
    };

    sensor@1 {
        compatible = "generic,sensor";
        reg = <1>;
        frequency = <24000000>;
        ti,cs-delay = <20>;
        label = "SENSOR_1";
    };
};

i suppose the above is acceptable for zephyr style of application programming
