Clock dumps are useful to analyze power and thermal issues. The following script can be run
      during the use case to get the frequency of all the subsystem.

1. Connect the USB using the following command.

        adb rootCopy to clipboard

        adb shellCopy to clipboard

        sleep 5 && while true; do echo \=\=\=\=\=\=\=\=\=\=\=\=\=\=\=\=\=\=\=; cat /proc/uptime; cat /sys/kernel/debug/clk/enabled_clocks; sleep 20; done > /data/enabled_clks.txt & //Unplug USB when PID is shown. Wait for 10 minutes to collect the log.Copy to clipboard
2. Insert the USB back to the device after 10 min, and stop the PID using the following
        commands.

        adb shell "kill [PID]"	
        Copy to clipboard

        adb pull /data/enabled_clks.txtCopy to clipboard

Note: If /sys/kernel/debug/clk/enabled\_clocks is unavailable, then
      use the path /sys/kernel/debug/clk/clk\_enabled\_list.
