linux LEDE 发行版上spi-bitbang功能dts文件如何配置？

Question

    gpio-spi {         status = "okay";        compatible = "spi-gpio";        #address-cells = <0x1>;        ranges;        gpio-sck = <&gpio0 14 1>;        gpio-miso = <&gpio0 15 1>;        gpio-mosi = <&gpio0 16 1>;        cs-gpios = <&gpio0 17 1>;        num-chipselects = <1>;        /* clients */        spidev@1 {            compatible = "spidev";            reg = <0>;            spi-max-frequency = <10000000>;        };    };以上有错误吗？
