  在修改Kernel 设备树支持时，max-frequency频率修改的范围是多少？怎么修改SDIO接口wifi的驱动电流？
  &sdmmc {
  max-frequency = <20000000>;
  bus-width = <4>;
  cap-sd-highspeed;
  cap-sdio-irq;
  keep-power-in-suspend;
  non-removable;
  sd-uhs-sdr50;
  no-1-8-v;
  supports-sdio;
  pinctrl-names = "default";
  pinctrl-0 = <&sdmmc0_clk &sdmmc0_cmd &sdmmc0_det &sdmmc0_bus4>;
  status = "okay";
  };
