      Linus Torvalds authored
      Pull GPIO updates from Linus Walleij:
       "This time very little driver changes but lots of core changes.
      
        We have some interesting cooperative work for ARM and Intel alike,
        making the GPIO subsystem more and more suitable for industrial
        systems and the like, in addition to the in-kernel users.
      
        We touch driver core (device properties) and lib/* by adding one
        simple string array free function, these are authored by Andy
        Shevchenko who is a well known and recognized core helpers maintainers
        so this should be fine.
      
        We also see some Android GKI-related modularization in the MXC
        drivers.
      
        Core changes:
      
         - The big core change is the updated (v2) userspace character device
           API.
      
           This corrects badly designed 64-bit alignment around the line
           events. We also add the debounce request feature. This echoes the
           often quotes passage from Frederick Brooks "The mythical man-month"
           to always throw one away, which we have seen before in things such
           as V4L2. So we put in a new one and deprecate and obsolete the old
           one.
      
         - All example tools in tools/gpio/* are migrated to the new API to
           set a good example. The libgpiod userspace library has been
           augmented to use this new API pretty much from day 1.
      
         - Some misc API hardening by using strn* function calls has been
           added as well.
      
         - Use the simpler IDA interface for GPIO chip instance enumeration.
      
         - Add device core function for counting string arrays in device
           properties.
      
         - Provide a generic library function kfree_strarray() that can be
           used throughout the kernel.
      
        Driver enhancements:
      
         - The DesignWare dwapb-gpio driver has been enhanced and now uses the
           IRQ handling in the gpiolib core.
      
         - The mockup and aggregator drivers have seen some substantial code
           clean-up and now use more of the core kernel inftrastructure.
      
         - Misc cleanups using dev_err_probe().
      
         - The MXC drivers (Freescale/NXP) can now be built modularized, which
           makes modularized GKI Android kernels happy"
