    Pull gpio updates from Bartosz Golaszewski:
     "We have a new GPIO multiplexer driver, bunch of driver updates and
      refactoring in the core GPIO library.
    
      GPIO core:
       - teach gpiolib to work with software nodes for HW description
       - remove ARCH_NR_GPIOS treewide as we no longer impose any limit on
         the number of GPIOS since the allocation became entirely dynamic
       - add support for HW quirks for Cirrus CS42L56 codec, Marvell NFC
         controller, Freescale PCIe and Ethernet controller, Himax LCDs and
         Mediatek mt2701
       - refactor OF quirk code
       - some general refactoring of the OF and ACPI code, adding new
         helpers, minor tweaks and fixes, making fwnode usage consistent
         etc.
    
      GPIO uAPI:
       - fix an issue where the user-space can trigger a NULL-pointer
         dereference in the kernel by opening a device file, forcing a
         driver unbind and then calling one of the syscalls on the
         associated file descriptor
    
      New drivers:
       - add gpio-latch: a new GPIO multiplexer based on latches connected
         to other GPIOs
    
      Driver updates:
       - convert i2c GPIO expanders to using .probe_new()
       - drop the gpio-sta2x11 driver
       - factor out common code for the ACCES IDIO-16 family of controllers
         and use this new library wherever applicable in drivers
       - add DT support to gpio-hisi
       - allow building gpio-davinci as a module and increase its maxItems
         property
       - add support for a new model to gpio-pca9570
       - other minor changes to various drivers"
