  参考ROCKCHIP说明书，编制如下配置文件，编译后系统仅显示SPI1.0，没有出现SPI1.1，请问哪里出现问题？
  &spi1 {
  status = "okay";
  pinctrl-names = "default";
  pinctrl-0 = <&spi1m0_pins>;
  #address-cells = <1>;
  #size-cells = <0>;
  spidev0@0 {
  compatible = "rockchip,spidev";
  spi-max-frequency = <50000000>;
  id = <0>;
  reg = <0>;
  };
  spidev1@1 {
  compatible = "rockchip,spidev";
  spi-max-frequency = <50000000>;
  id = <1>;
  reg = <1>;
  };
  
  };
  &pinctrl {
  spi1 {
  /omit-if-no-ref/
  spi1m0_pins: spi1m0-pins {
  rockchip,pins =
  /* spi1_cs0_m0 */
  <4 RK_PA5 2 &pcfg_pull_none>,
  /* spi1_clk_m0 */
  <4 RK_PA7 2 &pcfg_pull_none>,
  /* spi1_miso_m0 */
  <4 RK_PA0 2 &pcfg_pull_none>,
  /* spi1_mosi_m0 */
  <4 RK_PA1 2 &pcfg_pull_none>;
  };
  };
  };
