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
   - 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"
