Linus Torvalds b3c0eccb48 gpio updates for v6.11-rc1
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

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

     fail
