I've looked into using the same operating points for A23 and A33 for CPUfreq and I came to the conclusion that not all A23-based boards share the same operating points. You can find the fex files for the different boards here: https://github.com/linux-sunxi/sunxi-boards/tree/master/sys_config/a23 After gathering all supported frequencies/voltages for each A23-based boards, I found that only the following frequencies and voltages are supported by all A23-based boards: - 1008 MHz, 1220 mV - 816 MHz, 1120 mV - 600 MHz, 1040 mV Quentin -- Quentin Schulz, Free Electrons Embedded Linux and Kernel engineering http://free-electrons.com
