I disagree. 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
