命令行进行时钟的操作

依赖:

kernel 4.4: 需打开: CONFIG_ROCKCHIP_PM_TEST

使用说明:

cat /sys/pm_tests/clk_rate

get clk rate:
         echo get [clk_name] > /sys/pm_tests/clk_rate
set clk rate:
         echo rawset [clk_name] [rate(Hz)] > /sys/pm_tests/clk_rate
enable clk:
         echo open [clk_name] > /sys/pm_tests/clk_rate
disable clk:
         echo close [clk_name] > /sys/pm_tests/clk_rate
