Pull gpio updates from Bartosz Golaszewski:
 "There are two new drivers and support for more models in existing
  ones.

  The generic GPIO API has been reworked and all users converted
  which allowed us to move the fields specific to the generic GPIO
  implementation out of the high-level struct gpio_chip into its own
  structure that wraps the gpio_chip.

  Other than that, there's nothing too exciting. Mostly minor tweaks and
  fixes all over the place, some refactoring and some small new features
  in helper modules.

  GPIO core:
   - add support for sparse pin ranges to the glue between GPIO and
     pinctrl
   - use a common prefix across all GPIO descriptor flags for improved
     namespacing

  New drivers:
   - add new GPIO driver for the Nuvoton NCT6694
   - add new GPIO driver for MAX7360

  Driver improvements:
   - add support for Tegra 256 to the gpio-tegra186 driver
   - add support for Loongson-2K0300 to the gpio-loongson-64bit driver
   - refactor the gpio-aggregator module to expose its GPIO forwarder
     API to other in-kernel users (to enable merging of a new pinctrl
     driver that uses it)
   - convert all remaining drivers to using the modernized generic GPIO
     chip API and remove the old interface
   - stop displaying global GPIO numbers in debugfs output of controller
     drivers
   - extend the gpio-regmap helper with a new config option and improve
     its support for GPIO interrupts
   - remove redundant fast_io parameter from regmap configs in GPIO
     drivers that already use MMIO regmaps which imply it
   - add support for a new model in gpio-mmio: ixp4xx expansion bus
   - order includes alphabetically in a few drivers for better
     readability
   - use generic device properties where applicable
   - use devm_mutex_init() where applicable
   - extend build coverage of drivers by enabling more to be compiled
     with COMPILE_TEST enabled
   - allow building gpio-stmpe as a module
   - use dev_err_probe() where it makes sense in drivers

  Late driver fixes:
   - fix setting GPIO direction to output in gpio-mpfs

  Documentation:
   - document the usage of software nodes with GPIO chips

  Device-tree bindings:
   - Add DT bindings documents for new hardware: Tegra256, MAX7360
   - Document a new model in Loongson bindings: LS2K0300
   - Document a new model using the generic GPIO binding: IXP4xx
   - Convert the DT binding for fsl,mxs-pinctrl to YAML
   - fix the schema ID in the "trivial" GPIO schema
   - describe GPIO hogs in the generic GPIO binding"
