Subject: [GIT PULL] gpio updates for v6.16-rc1
From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>
Linus,
Here's the PR containing updates for the GPIO subsystem for this cycle.
We have three new drivers, some refactoring in the GPIO core, lots of
various changes across many drivers, new configfs interface for the
virtual gpio-aggregator module and DT-bindings updates.
The treewide conversion of GPIO drivers to using the new value setter
callbacks is ongoing with another round of GPIO drivers updated. You will
also see these commits coming in from other subsystems as with the
relevant changes merged into mainline last cycle, I've started converting
GPIO providers located elsewhere than drivers/gpio/.
Details are in the signed tag. Please consider pulling
Thanks,
Bartosz Golaszewski

gpio: timberdale: select GPIOLIB_IRQCHIP (2025-05-22 10:00:08 +0200)
----------------------------------------------------------------
gpio updates for v6.16-rc1
GPIO core:
- use more lock guards where applicable
- refactor GPIO ACPI code and shrink it in the process by 8%
- move GPIO ACPI quirks into a separate file
- remove unneeded #ifdef
- convert GPIO devres helpers to using devm_add_action() where applicable
which shrinks and simplifies the code
- refactor GPIO descriptor validation in GPIO consumer interfaces
- don't allow setting values on input lines in the GPIO core which will
take off the burden from GPIO drivers of checking this down the line
- provide gpiod_is_equal() as a way of safely comparing two GPIO
descriptors (the only current user is in regulator core)
New drivers:
- add the GPIO module for the max77759 multifunction device
- add the GPIO driver for the VeriSilicon BLZP1600 GPIO controller
- add the GPIO driver for the Spacemit K1 SoC
Driver improvements:
- convert more drivers to using the new GPIO line value setter callbacks
- convert more drivers to making the irq_chip immutable as is recommended
by the interrupt subsystem
- extend build testing coverage by enabling more modules to be built with
COMPILE_TEST=y
- extend the gpio-aggregator module with a configfs interface that makes
the setup easier for user-space than the existing driver-level sysfs
attributes and also adds more advanced configuration features (such as
referring to aggregated lines by their original names or modifying
their names as exposed by the aggregated chip)
- add a missing mutex_destroy() in gpio-imx-scu
- add an OF polarity quirk for s5m8767
- allow building gpio-vf610 as a loadable module
- make gpio-mxc not hardcode its GPIO base number with GPIO SYSFS
interface disabled (another small step towards getting rid of the global
GPIO numberspace)
- add support for level-triggered interrupts to gpio-pca953x
- don't double-check the ngpios property in gpio-ds4520 as GPIO core
already does it
- don't double-check the number of GPIOs in gpio-imx-scu as GPIO core
already does it
- remove unused callbacks from gpio-max3191x
DT bindings:
- add device-tree bindings for max77759, spacemit,k1 and blzp1600 (new
drivers added this cycle)
- document more properties for gpio-vf610 and gpio-tegra186
- document a new pca95xx variant
- fix style of examples in several GPIO DT-binding documents
Misc:
- TODO list updates
