Merge tag 'gpio-updates-for-v6.5' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "We have two new drivers, some improvements to the core code, lots of
  different updates to existing GPIO drivers and some dt-bindings on
  top.

  There's nothing controversial in here and almost everything has been
  in next for more than a week (95% a lot longer than this). The only
  thing that has spent less time in next is a new driver so no risk of
  regressions.

  The single merge pulls in changes that remove all usage of global GPIO
  numbers from arch/arm/mach-omap.

  Core GPIO library:
   - remove unused symbols
   - don't spam the kernel log with messages about hogs
   - remove old sysfs API cruft
   - improve handling of GPIO masks

  New drivers:
   - add a driver for the BlueField-3 GPIO controller
   - add GPIO support for the TPS65219 PMIC

  Driver improvements:
   - extend the gpio-aggregator driver to support ramp-up/ramp-down
     delay
   - remove unnecessary CONFIG_OF guards from gpio-aggregator
   - readability improvements in gpio-tangier
   - switch i2c drivers back to using probe() now that it's been
     converted in the i2c subsystem to not taking the id parameter
   - remove unused inclusions of of_gpio.h in several drivers
   - make pm ops static in gpio-davinci and fix a comment
   - use more devres in drivers to shrink and simplify the code
   - add missing include in gpio-sa1100
   - add HAS_IOPORT KConfig dependency where needed
   - add permissions checks before accessing pins in gpio-tegra186
   - convert the gpio-zynq driver to using immutable irqchips
   - preserve output settings set by the bootloader in gpio-mpc8xxx

  Selftests:
   - tweak the variable naming in script tests

  Device tree updates:
   - convert gpio-mmio and gpio-stmpe to YAML
   - add parsing of GPIO hogs to gpio-vf610
   - add bindings for the Cirrus EP93xx GPIO controller
   - add gpio-line-names property to the gpio-pca9570 bindings
   - extend the binding for x-powers,axp209 with another block"
