Merge tag 'gpio-updates-for-v7.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "There are two new drivers and some changes to GPIO core but mostly
  just GPIO driver updates across a wide array of files, adding support
  for new models as well as various refactoring changes. Nothing
  controversial and everything has spent a good measure of time in
  linux-next.

  GPIOLIB core:
   - shrink the GPIO bus driver stub code
   - rework software node support for "undefined" software nodes
   - provide and use devm_fwnode_gpiod_get_optional()
   - only compile the OF quirk for MT2701 when needed

  New drivers:
   - add the GPIO driver for ROHM bd72720
   - add the gpio-line-mux driver providing 1-to-many mapping for a
     single real GPIO

  Driver changes:
   - refactor gpio-pca9570: use lock guard, add missing headers, use
     devres consistently
   - add support for a new model (G7 Aspeed sgpiom) to the aspeed-sgpio
     driver along with some prerequisite refactoring
   - use device_get_match_data() where applicable and save some lines
   - add support for more models to gpio-cadence
   - add the compatible property to reset-gpio and use it in shared GPIO
     management
   - drop unnecessary use of irqd_get_trigger_type() in gpio-max77759
   - add support for a new variant to gpio-pca953x
   - extend build coverage with COMPILE_TEST for more drivers
   - constify configfs structures in gpio-sim and gpio-virtuser
   - add support for the K3 SoC to gpio-spacemit
   - implement the missing .get_direction() callback in gpio-max77620
   - add support for Tegra264 to gpio-tegra186
   - drop unneeded MODULE_ALIAS() from gpio-menz127

  DT bindings:
   - document support for the opencores GPIO controller in gpio-mmio
   - document new variants for gpio-pca953x

  Documentation:
   - extensively describe interrupt source detection for gpio-pca953x
     and add more models to the list of supported variants"
