Subject: [GIT PULL] clk: convert drivers from deprecated round_rate() to
determine_rate() for v6.18
Hi Stephen and Michael,
Given the large number of patches that I have posted for the
round_rate() to determine_rate() conversion, and to avoid spamming
large numbers of people's inboxes where a v2 was needed on only a few
patches in a series with 114 patches, I submitted a v2 for only the
patches that needed it. Additionally, some of the other patches in the
large series have already been picked up by some of the clk
submaintainers, so should be excluded as well. This makes it more
complicated to merge everything, so I collected the most recent
versions of the conversion work for drivers/clk using the following b4
commands:
MAILDIR=$(mktemp -d)
b4 am -o "${MAILDIR}" --cherry-pick 1-1,3-3,5-8 \
20250828-clk-round-rate-v2-v1-0-b97ec8ba6cc4@...hat.com

Additionally I included the patch series for drivers/clk/ti and
drivers/clk/tegra since this is all related work.
Note the v2 clk/tegra series that I posted mistakenly had extra Link
tags added when I posted them to the mailinglist. I dropped the Link
tag for these commits so that those tags don't appear in the git history
in Linus's tree.
The following changes since commit 8f5ae30d69d7543eee0d70083daf4de8fe15d585:

clk: scmi: migrate round_rate() to determine_rate() (2025-09-08 12:50:56 -0400)
----------------------------------------------------------------
The round_rate() clk ops is deprecated in the clk framework in favor
of the determine_rate() clk ops, so let's go ahead and convert the
various clk drivers using the Coccinelle semantic patch posted below.
I did some minor cosmetic cleanups of the code in some cases.
Coccinelle semantic patch:
virtual patch

Note that I used coccinelle 1.2 instead of 1.3 since the newer version
adds unnecessary braces as described in this post.
