Linus Torvalds d701782152 gpio updates for v7.0-rc1
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

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:
