Core GPIOLIB:
- drop several OF interfaces after moving a significant part of the code to
using software nodes
- remove more interfaces referring to the global GPIO numberspace that we're
getting rid of
- improvements in the gpio-regmap library
- add helper for GPIO device reference counting
- remove unused APIs
- minor tweaks like sorting headers alphabetically
Extended support in existing drivers:
- add support for Tegra 234 PMC to gpio-tegra186
Driver improvements:
- migrate the 104-dio/idi family of drivers to using the regmap-irq API
- migrate gpio-i8255 and gpio-mm to the GPIO regmap API
- clean-ups in gpio-pca953x
- remove duplicate assignments of of_gpio_n_cells in gpio-davinci, gpio-ge,
gpio-xilinx, gpio-zevio and gpio-wcd934x
- improvements to gpio-pcf857x: implement get/set_multiple callbacks, use
generic device properties instead of OF + minor tweaks
- fix OF-related header includes and Kconfig dependencies in gpio-zevio
- dynamically allocate the GPIO base in gpio-omap
- use a dedicated printf specifier for printing fwnode info in gpio-sim
- use dev_name() for the GPIO chip label in gpio-vf610
- other minor tweaks and fixes
Documentation:
- remove mentions of legacy API from comments in various places
- convert the DT binding documents to YAML schema for Fujitsu MB86S7x, Unisoc
GPIO and Unisoc EIC
- document the Unisoc UMS512 controller in DT bindings

Merge tag 'gpio-updates-for-v6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux
Pull gpio updates from Bartosz Golaszewski:
"A rather small update, there are no new drivers, just improvements and
refactoring in existing ones.
Thanks to migrating of several drivers to using generalized APIs and
dropping of OF interfaces in favor of using software nodes we're
actually removing more code than we're adding.
Core GPIOLIB:
- drop several OF interfaces after moving a significant part of the
code to using software nodes
- remove more interfaces referring to the global GPIO numberspace
that we're getting rid of
- improvements in the gpio-regmap library
- add helper for GPIO device reference counting
- remove unused APIs
- minor tweaks like sorting headers alphabetically
Extended support in existing drivers:
- add support for Tegra 234 PMC to gpio-tegra186
Driver improvements:
- migrate the 104-dio/idi family of drivers to using the regmap-irq
API
- migrate gpio-i8255 and gpio-mm to the GPIO regmap API
- clean-ups in gpio-pca953x
- remove duplicate assignments of of_gpio_n_cells in gpio-davinci,
gpio-ge, gpio-xilinx, gpio-zevio and gpio-wcd934x
