arm_freq Frequency of the ARM CPU in MHz. The default value is 700.

core_freq Frequency of the GPU processor core in MHz. It has an impact on CPU performance, since it drives the L2 cache. The default value is 250.

sdram_freq Frequency of the SDRAM in MHz. The default value is 400.

gpu_freq Sets core_freq, h264_freq, isp_freq, and  v3d_freq together. The default value is 250.

h264_freq Frequency of the hardware video block in MHz. The default value is 250.

isp_freq Frequency of the image sensor pipeline block in MHz. The default value is 250.

v3d_freq Frequency of the 3D block in MHz. The default value is 250.

arm_freq_min Minimum value of arm_freq used for dynamic frequency clocking. The default value is 700.

core_freq_min Minimum value of core_freq used for dynamic frequency clocking. The default value is 250.

sdram_freq_min Minimum value of sdram_freq used for dynamic frequency clocking. The default value is 400.
