Subject: [GIT PULL] 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 command to
collect up this series:

    b4 am --cherry-pick 1-13,17-23 \
        20260108-clk-divider-round-rate-v1-0-535a3ed73bf3@...hat.com

I skipped some of the patches that have already been picked up by
others. The last two patches in that series that actually remove the
deprecated functions will need to go in during the next dev cycle.

One thing that I want to call out in this pull is the change to
drivers/rtc/rtc-ac100.c, which is all clk related.


The following changes since commit 8f0b4cce4481fb22653697cced8d0d04027cb1e8:

  clk: zynqmp: divider: convert from divider_round_rate() to divider_determine_rate() (2026-01-21 16:32:09 -0500)

----------------------------------------------------------------
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.
