Hi Kever,
Strange… Then I tested a year ago I saw, that writing into bwadj registers had
no effect
for some PLLs. But now I did another test. See patch and output. Looks like
rk3188 allow
writing into bwadj fields.
So I do something like 'priv->has_bwadj = 1' in the rk3188_clk_probe() and
se
Hi Alex,
I think it will be better to update the rk3188_clk_probe() function
instead of
what you have modified if the RK3188 and RK3188A has the same PLL(I'm
not sure
about it now).
Thanks,
- Kever

Empirically, I found that DPLL on rk3188 has bwadj registers.
Configuring DPLL with bwadj increase DPLL stability. Because
of DPLL provide clock for ethernet, enabling bwaj reduces
the number of errors on the ethernet.
