Pull gpio updates from Bartosz Golaszewski:
 "The majority of added lines are two new modules: the GPIO virtual
  consumer module that improves our ability to add automated tests for
  the kernel API and the "sloppy" logic analyzer module that uses the
  GPIO API to implement a coarse-grained debugging tool for useful for
  remote development.

  Other than that we have the usual assortment of various driver
  extensions, improvements to the core GPIO code, DT-bindings and other
  documentation updates as well as an extension to the interrupt
  simulator:

  GPIOLIB core:
   - rework kfifo handling rework in the character device code
   - improve the labeling of GPIOs requested as interrupts and show more
     info on interrupt-only GPIOs in debugfs
   - remove unused APIs
   - unexport interfaces that are only used from the core GPIO code
   - drop the return value from gpiochip_set_desc_names() as it cannot
     fail
   - move a string array definition out of a header and into a specific
     compilation unit
   - convert the last user of gpiochip_get_desc() other than GPIO core
     to using a safer alternative
   - use array_index_nospec() where applicable

  New drivers:
   - add a "virtual GPIO consumer" module that allows requesting GPIOs
     from actual hardware and driving tests of the in-kernel GPIO API
     from user-space over debugfs
   - add a GPIO-based "sloppy" logic analyzer module useful for "first
     glance" debugging on remote boards

  Driver improvements:
   - add support for a new model to gpio-pca953x
   - lock GPIOs as interrupts in gpio-sim when the lines are requested
     as irqs via the simulator domain + some other minor improvements
   - improve error reporting in gpio-syscon
   - convert gpio-ath79 to using dynamic GPIO base and range
   - use pcibios_err_to_errno() for converting PCIBIOS error codes to
     errno vaues in gpio-amd8111 and gpio-rdc321x
   - allow building gpio-brcmstb for the BCM2835 architecture

  DT bindings:
   - convert DT bindings for lsi,zevio, mpc8xxx, and atmel to DT schema
   - document new properties for aspeed,gpio, fsl,qoriq-gpio and
     gpio-vf610
   - document new compatibles for pca953x and fsl,qoriq-gpio

  Documentation:
   - document stricter behavior of the GPIO character device uAPI with
     regards to reconfiguring requested line without direction set
   - clarify the effect of the active-low flag on line values and edges
   - remove documentation for the legacy GPIO API in order to stop
     tempting people to use it
   - document the preference for using pread() for reading edge events
     in the sysfs API

  Other:
   - add an extended initializer to the interrupt simulator allowing to
     specify a number of callbacks callers can use to be notified about
     irqs being requested and released"
