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"
