-## Revision 14, 2012/10/22
-##
-## Details taken from the eLinux wiki
-## For up-to-date information please refer to wiki page.
-##
-## Wiki Location : http://elinux.org/RPi_config.txt
-##
-##
-## 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.
-##
-## WARNING: Setting the following combination of parameters will set a
-## permanent bit within the SOC and your warranty is void.
-## over_voltage>0, and at least one of the following:
-## force_turbo=1
-## current_limit_override=0x5A000020
-## temp_limit>85
-##
-## Overclock settings will be disabled at runtime if the SoC reaches temp_limit

-## Enables turbo mode from boot for the given value in seconds (up to 60)
-## or until cpufreq sets a frequency. Can help with sdcard corruption if
-## overclocked.
-##
-## Default 0
-##
-#initial_turbo=0
-
-## temp_limit
-## Overheat protection. Sets clocks and voltages to default when the SoC
-## reaches this Celsius value.
-## Setting this higher than default voids warranty.
-##
-## Default 85
-##
-#temp_limit=85
-
-## arm_freq
-## Frequency of ARM in MHz.
-##
-## Default 700.

-
-## gpu_freq
-## Sets core_freq, h264_freq, isp_freq, v3d_freq together.
-##
-## Default 250.
-##
-#gpu_freq=250
-
-## core_freq
-## Frequency of GPU processor core in MHz. It has an impact on ARM
-## performance since it drives L2 cache.
-##
-## Default 250.
-##
-#core_freq=250
-
-## core_freq_min
-## Minimum frequency of GPU processor core in MHz (used for dynamic

-
-## sdram_freq
-## Frequency of SDRAM in MHz.
-##
-## Default 400.
-##
-#sdram_freq=400
-
-## sdram_freq_min
-## Minimum frequency of SDRAM in MHz (used for dynamic clocking).
-##
-## Default 400.
-##
-#sdram_freq_min=400
-
-## avoid_pwm_pll
-## Unlink core_freq from the rest of the gpu. Analog audio should still
-## work, but from a fractional divider, so lower quality.
-##
-## Value Description
-## -------------------------------------------------------------------------
-## 0 Linked core_freq (Default)
-## 1 Unlinked core_freq
