      打开平台的clock配置dts文件, 位于[sdk]/lichee/linux-3.10/arch/arm/boot/dts/, 文件名是sun3iw1p1-clk.dtsi
      找到pll cpu, 将assigned-clock-rates修改为目标的频率, 单位是Hz. 如下:

      clk_pll_cpu: pll_cpu {
      #clock-cells = <0>;
      compatible = "allwinner,sunxi-pll-clock";
      lock-mode = "none";
      assigned-clock-rates = <696000000>;
      clock-output-names = "pll_cpu";
      };
