SPI on Toradex Verdin iMX8M Plus

Question

I'm new to device tree and I'm trying to get spidev0.1, spidev 1.0, spidev 1.1, spidev 2.0 and spidev2.1. Currently I only have spidev0.0 in /dev.

I've tried to modify my device tree as follows but it doesn't work:

imx8mp-verdin-yavia.dtsi

/* Verdin SPI_1 */
&ecspi1 {
    status = "okay";
    spidev@0 {
        compatible = "toradex,evalspi";
        reg = <0>;
        spi-max-frequency = <10000000>;
        status = "okay";
    };
    spidev@1 {
        compatible = "toradex,evalspi";
        reg = <1>;
        spi-max-frequency = <10000000>;
        status = "okay";
    };
    spidev@2 {
        compatible = "toradex,evalspi";
        reg = <2>;
        spi-max-frequency = <10000000>;
        status = "okay";
    };
      };

I also have this overlay that I haven't modified.
