Subject: [PATCH 0/2] clk: sunxi: Fix APBS clock for Allwinner A80

Hi everyone,

When I did the A80 PRCM support, I failed to notice the A80's APBS clock
was not the same as the A23's APB0 clock. The former is a zero-based
divider, while the latter is a power-of-two divider. But the lowest 2
dividers are the same.

The hardware defaults to the lowest setting, or a /1 divider. Since the
child gates do not propagate clk_set_rate up, and no consumers here do
clk_set_rate, this actually works.

I realized my mistake while reviewing the A83T's PRCM patches. The A83T
shares the same PRCM clocks as the A80.


Regards
ChenYu
