##  Description:
##    Details of each setting are described with each section that begins with
##    a double hashed comment ('##')
##    It is up to the user to remove the single hashed comment ('#') from each
##    option they want to enable, and to set the specific value of that option.
##
##  Overclock settings will be disabled at runtime if the SoC reaches temp_limit

##  gpu_freq = pll_freq / [even number]
##
##  The effective gpu_freq is automatically rounded to nearest even integer, so
