After reverting those 5 commits from Chen-Yu I was able to boot again:
clk: sunxi-ng: Support fixed post-dividers on NM style clocks
clk: sunxi-ng: sun8i: a83t: Add /2 fixed post divider to audio PLL
clk: sunxi-ng: sun8i: a83t: Use sigma-delta modulation for audio PLL
clk: sunxi-ng: Support fixed post-dividers on MP style clocks
clk: sunxi-ng: sun50i: a64: Add 2x fixed post-divider to MMC module clocks
I allready tried to fix it with making them save against zero:
if (cmp->common.features & CCU_FEATURE_FIXED_POSTDIV && \
rate *= cmp->fixed_post_div;
But that didn't help.
It took me some time, but I have now a few more infos:
Right now the code breaks at this point here , with this clock .
If we have a look now at the clock config , we see here a table which
is an u8 array and also a fixed_predivs struct.
If we have a look at the function call where it breaks , shouldn't
the table be a clk_div_table struct instead of an u8?
The a31s is the only board where we have this combination of a
fixed_predivs and a table.
