[GIT PULL] gpio updates for v7.3-rc1 - take 2
From: Bartosz Golaszewski

Linus,
This is the fixed version of the primary PR from the GPIO tree for this merge
window. It's essentially the same except that it contains two additional merge
commits: one pulling in the upstream v7.2 tag in order to address a conflict
between my for-next and your master branches. The second pulls in an immutable
branch from Mark Brown I missed before but which contains a commit on which
some of the regmap changes depend.
There's one new driver for the Realtek DHC RTD1625 GPIO controller. If adding
it, reverting it and then adding it again raises your eyebrow: this was done
becuase the initial implementation - while correct - didn't use the gpio-regmap
abstraction that suited it nicely. The conversion was done after I had already
merged v7.2-rc2 into my tree so instead of rebasing, I went with a revert for
a cleaner git blame output.
The merges you see - other than pulling in your upstream tags with conflicting
fixes - are for a PR from Arnd containing his work on further isolating legacy
GPIO APIs and the fw_devlink support for software nodes that will go upstream
via the driver core tree.
Nothing else really stands out, details are in the signed tag. Please consider
pulling.
Thanks,
Bartosz

Merge tag 'v7.2' of git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux into gpio/for-next (2026-08-18 14:21:04 +0200)
----------------------------------------------------------------
gpio updates for v7.3-rc1
GPIO core:
- extend the gpio-regmap abstraction layer with more features allowing users
to override configuration setting, translate register values and masks and
enable/disable interrupts
- extend GPIO kunit tests with suites verifying probe ordering by software
node devlink support and software node hogs
- shrink GPIO kunit initialization code
- coding style updates (remove commas from sentinels where applicable)
- with all users now converted treewide to using real firmware node links for
software node GPIO lookup: remove the deprecated label-matching mechanism
from from GPIO core
- drop redundant return value check of nonseekable_open() in gpiolib-cdev
- use IRQ trigger helpers where applicable
Driver updates:
- refactor error paths and logging in gpio-nomadik
- use more modern interfaces for getting resources in gpio-rockchip,
gpio-bt8xx and gpio-pca9570
- add missing MODULE_DEVICE_TABLE() to gpio-sifive and gpio-vf610
- drop unused FILONOFF macro from gpio-rcar
- extend build coverage of ioport GPIO drivers with COMPILE_TEST=y
- only enable the gpio-rtd driver by default with ARCH_REALTEK=y to avoid
bloating the build
- refactor coding style in several drivers
- use correct endianess translation in gpio-pcf85x
- add wake-up interrupt support to gpio-mvebu
- apply initial value in direction output setter in gpio-by-pinctrl
Misc:
- replace linux/gpio.h inclusions treewide with linux/gpio/legacy.h which now
exports all the deprecated APIs
- select GPIOLIB_LEGACY in Kconfig where required treewide
- use software nodes for gpio-keys in MFD drivers
Devicetree bindings:
- describe the realtek rtd1625 GPIO controller
- document new models for gpio-pca95xx and gpio-cadence
- document new property in gpio-rockchip
