Pull gpio updates from Bartosz Golaszewski:
 "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

Move the ppc4xx gpio driver out of arch/powerpc/platforms/44x/ into
drivers/gpio/gpio-ppc44x.c. The driver has no architecture-specific
dependencies and follows the same pattern as other PowerPC GPIO
drivers already in drivers/gpio/ (e.g. gpio-mpc8xxx, gpio-mpc5200).

- Renamed Kconfig symbol from PPC4xx_GPIO to GPIO_PPC44X
- Updated ppc44x_defconfig and warp_defconfig to use the new symbol
- Marked the new option as tristate (was bool) since the driver
  supports module build via module_platform_driver()

gpio: add kunit test cases for the GPIO subsystem 2026-05-26T09:19:54+00:00 Bartosz Golaszewski bartosz.golaszewski@oss.qualcomm.com 2026-05-22T13:42:18+00:00 a6d2a3b403cbcbcdb3ffdb63e52ac090c1003d05 Add a module containing kunit test cases for GPIO core. The idea is to use it to test functionalities that can't easily be tested from user-space with kernel selftests or GPIO character device test suites provided by the libgpiod package. For now add test cases that verify software node based lookup and ensure that a GPIO provider unbinding with active consumers does not cause a crash.
