Hi Dong

one can refer to Chapter 23 CPU Frequency Scaling (CPUFREQ) Driver

in attached Linux Manual, which changes CPU frequency and dts file

linux/arch/arm/boot/dts/imx6q.dtsi, cpu0: cpu@0.. "operating-points":

linux-imx.git - i.MX Linux Kernel

In older linux releases one can try kernel boot parameter "arm_freq"

described in Table 6. Kernel Boot Parameters Linux Release Notes.

Best regards
igor
