Subject: [PATCH 00/27] clk: remove deprecated API divider_round_rate() and
friends
Here's a series that gets rid of the deprecated APIs
divider_round_rate(), divider_round_rate_parent(), and
divider_ro_round_rate_parent() since these functions are just wrappers
for the determine_rate variant.
Note that when I converted some of these drivers from round_rate to
determine_rate, this was mistakenly converted to the following in some
cases:
req->rate = divider_round_rate(...)
This is invalid in the case when an error occurs since it can set the
rate to a negative value. So this series fixes those bugs and removes
the deprecated APIs all in one go.
Three of the patches ended up being a more complicated migration, and I
put them as the first three patches in this series (clk: sophgo:
cv18xx-ip), (clk: sunxi-ng), and (rtc: ac100). The remaining patches I
feel are all straight forward.
Merge strategy
==============
Only three of the patches are outside of drivers/clk (drm/msm, phy, and
rtc). For simplicity, I think it would be easiest if Stephen takes this
whole series through the clk tree. Subsystem maintainers please leave an
Acked-by for Stephen. Thanks!
