SPI на Toradex Verdin iMX8M Plus

Question

Я новичок в дереве устройств и пытаюсь получить spidev0.1, spidev 1.0, spidev 1.1, spidev 2.0 и spidev2.1. В настоящее время у меня есть только spidev0.0 в /dev.

Я попытался изменить дерево устройств следующим образом, но это не сработало:

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";
    };
      };

У меня также есть это наложение, которое я не изменил.
