[PATCH 00/21] treewide: remove unneeded 'fast_io' parameter in regmap_config

[PATCH 00/21] treewide: remove unneeded 'fast_io' parameter in regmap_config

[Wolfram Sang]

While working on a driver using regmap with MMIO, I wondered if I need
to set 'fast_io' in the config. Turned out I don't need to, so I added
documentation for it with commit ffc72771ff6e ("regmap: Annotate that
MMIO implies fast IO").

This series fixes the existing users in the tree which needlessly set
the flag. They have been found using this coccinelle script:

===

@ match @
expression dev, clk, regs;
identifier config;
@@

(
	regmap_init_mmio(dev, regs, &config)
|
	devm_regmap_init_mmio(dev, regs, &config)
|
	regmap_init_mmio_clk(dev, clk, regs, &config)
|
	devm_regmap_init_mmio_clk(dev, clk, regs, &config)
)

@ fix depends on match @
identifier match.config;
@@

	struct regmap_config config = {
-	.fast_io = true,
	};

===

It misses occasions where 'config' is an expression and not an
identifier. These are rare, though, I can fix them manually later. The
advantage of this approach is that it produces no false positives to the
best of my knowledge.

Please apply individually per subsystem. There are no dependencies and
buildbot is happy. Patches are based on 6.17-rc1

Happy hacking,

   Wolfram

Looks fine to me, just a little heads up: the following patch
https://lore.kernel.org/all/20250812092618.14270-1-andrea.porta@suse.com/

adds other two regmap_config with fast_io set to true, so we can
get rid of them too. I can do it in my patch in case I have to send a
second revision, or you can amend yours to cope with my changes and set
my patch as a prerequisite. I guess that it's easier for me since
I have only a single patch, while yours is a big patchset so better
to avoid the noise of a second revision.

Many thanks,
Andrea

        commit: 37533933bfe92cd5a99ef4743f31dac62ccc8de0

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Should drivers/clk/sprd/common.c also be updated as well?

Thank you!

> Should drivers/clk/sprd/common.c also be updated as well?

fix the remaining few ones manually, but I didn't get to that until now.

Happy hacking,
