Subject: [GIT PULL] gpio updates for v6.17-rc1
From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>
Linus,
Here is the big pull-request for the GPIO subsystem for v6.17-rc1. There
will be at least one more later into the merge window, I'll talk about it
in a minute.
There's one new driver (Apple SMC) and extensions to existing drivers for
supporting new HW models. A lot of different impovements across drivers
and in core GPIO code. Details on that are in the signed tag as usual.
We managed to remove some of the legacy APIs. Arnd Bergmann started to
work on making the legacy bits optional so that we may compile them only
for older platforms that still really need them.
Rob Herring has done a lot of work to convert legacy .txt dt-bindings for
GPIO controllers to YAML. There are only a few left now in the GPIO tree.
A big part of the commits in this PR concern the conversion of GPIO
drivers to using the new line value setter callbacks. This conversion
is now complete treewide (unless I've missed something) and once all the
changes from different trees land in mainline, I'll send you another PR
containing a commit dropping the legacy callbacks from the tree.
On that note: the commit I mentioned above is already on the list[1]. I
have a second one that also renames the new callbacks back to their
original name[2]. This is a result of a simple sed over all source files
and a skim over the changes to make sure everything looks ok and to
adjust the formatting. I don't think it makes sense to send 4300+ lines
of diff to the mailing list, Cc'ing 200+ maintainers if all it does is
a simple treewide rename, so would you be willing to accept this commit
too as part of my second PR in order to avoid hundreds of small renaming
patches over the course of the next releases? FYI: it's not in next yet
but it passed all the regular autobuilder tests in my devel branch.
As the quest to pay back technical dept never really ends, we're starting
another set of interface conversions, this time it's about moving fields
specific to only a handful of drivers using the gpio-mmio helper out of
the core gpio_chip structure that every controller implements and uses.
This cycle we introduce a new set of APIs and convert a few drivers under
drivers/gpio/, next cycle we'll convert remaining modules treewide (in
gpio, pinctrl and mfd trees) and finally remove the old interfaces and
move the gpio-mmio fields into their own structure wrapping gpio_chip.
One last change I should mention here is the rework of the sysfs
interface. In 2016, we introduced the GPIO character device as the
preferred alternative to the sysfs class under /sys/class/gpio. While it
has seen a wide adoption with the help of its user-space counterpart -
libgpiod - there are still users who prefer the simplicity of sysfs. As
far as the GPIO subsystem is concerned, the problem is not the existince
of the GPIO class as such but rather the fact that it exposes the global
GPIO numbers to the user-space, stopping us from ever being able to
remove the numberspace from the kernel. To that end, this release we
introduced a parallel, limited sysfs interface that doesn't expose these
numbers and only implements a subset of features that are relevant to the
existing users. This is a result of several discussions over the course
of last year and should allow us to remove the legacy part some time in
the future.
Please consider pulling.
Thanks,
Bartosz

MIPS: alchemy: gpio: use new GPIO line value setter callbacks for the remaining chips (2025-07-28 08:03:08 +0200)
----------------------------------------------------------------
gpio updates for v6.17-rc1
GPIOLIB core:
- introduce a parallel, limited sysfs user ABI that doesn't expose the
global GPIO numbers to user-space while maintaining backward
compatibility with the end goal of it completely replacing the existing
interface, allowing us to remove it
- remove the legacy devm_gpio_request() routine which has no more users
- start the process of allowing to compile-out the legacy parts of the
GPIO core for users who don't need it by introducing a new Kconfig
option: GPIOLIB_LEGACY
- don't use global GPIO numbers in debugfs output from the core code
(drivers still do it, the work is ongoing)
- start the process of moving the fields specific to the gpio-mmio helper
out of the core struct gpio_chip into their own structure that wraps
it: create a new header with modern interfaces and convert several
drivers to using it
- remove the platform data structure associated with the gpio-mmio helper
from the kernel after having converted all remaining users to generic
device properties
- remove legacy struct gpio definition as it has no more users
New drivers:
- add the GPIO driver for the Apple System Management Controller
Driver improvements:
- add support for new models to gpio-adp5585, gpio-tps65219 and
gpio-pca953x
- extend the interrupt support in gpio-loongson-64bit
- allow to mark the simulated GPIO lines as invalid in gpio-sim
- convert all remaining GPIO drivers to using the new GPIO value setter
callbacks
- convert gpio-rcar to using simple device power management ops callbacks
- don't check if current direction of a line is output before setting
the value in gpio-pisosr and ti-fpc202: the GPIO core already handles
that
- also drop unneeded GPIO range checks in drivers, the core already makes
sure we're within bounds when calling driver callbacks
- use dev_fwnode() where applicable across GPIO drivers
- set line value in gpio-zynqmp-modepin and gpio-twl6040 when the user
wants to change direction of the pin to output even though these
drivers don't need to do anything else to actually set the direction,
otherwise a call like gpiod_direction_output(d, 1) will not result in
the line driver high
- remove the reduntant call to pm_runtime_mark_last_busy() from
gpio-arizona
- use lock guards in gpio-cadence and gpio-mxc
- check the return values of regmap functions in gpio-wcd934x and
gpio-tps65912
- use better regmap interfaces in gpio-wcove and gpio-pca953x
- remove dummy GPIO chip callbacks from several drivers in cases where
the GPIO core can already handle their absence
- allow building gpio-palmas as a module
Fixes:
- use correct bit widths (according to the documentation) in gpio-virtio
Device-tree bindings:
- convert several of the legacy .txt documents for many different devices
to YAML, improving automatic validation
- create a "trivial" GPIO DT schema that covers a wide range of simple
hardware that share a set of basic GPIO properties
- document new HW: Apple MAC SMC GPIO block and adp5589 I/O expander
- document a new model for pca95xx
- add and/or remove properties in YAML documents for gpio-rockchip,
fsl,qoriq-gpio, arm,pl061 and gpio-xilinx
Misc:
- some minor refactoring in several places, adding/removing forward
declarations, moving defines to better places, constify the arguments
in some functions, remove duplicate includes, etc.
- documentation updates
