Subject: [GIT PULL v2] clk: remove deprecated API divider_round_rate() and
 friends for v6.20

Hi Stephen,

Here's a PULL for this large series that continues the work to remove
some deprecated round_rate APIs. I used the following b4 commands to
collect up this series:

    b4 am --cherry-pick 1-2,4-13,17-23 \
        20260108-clk-divider-round-rate-v1-0-535a3ed73bf3@...hat.com
    b4 am 20260122-rtc-ac100-divider-round-rate-v2-1-044f8b493c35@...hat.com

I skipped the patches that have already been picked up by others. The
two patches that actually remove the deprecated functions from drivers/clk/
will need to go in during the next dev cycle.

The only change since the v1 PULL is to drivers/rtc/rtc-ac100.c:
- Fix two cases of brace inbalances around if/else
- Picked up an Acked-by from Alexandre

Details are in the signed tag.

Thanks!

  rtc: ac100: convert from divider_round_rate() to divider_determine_rate() (2026-01-22 10:49:10 -0500)

----------------------------------------------------------------
clk: remove deprecated API divider_round_rate() and friends for v6.20

Here's a series that lays the groundwork to 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.

We need to wait for some other changes to land in Linus's tree via the
phy tree before we can actually remove these functions. We should be
able to do that during the next development cycle.

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.

Note that this also contains a clk-specific change to
drivers/rtc/rtc-ac100.c, and that patch carrys an Acked-by from
Alexandre.
