    Pull gpio updates from Linus Walleij:
     "This is the big bulk of GPIO changes queued for the v4.2 kernel
      series:
    
       - a big set of cleanups to the aged sysfs interface from Johan
         Hovold.  To get these in, v4.1-rc3 was merged into the tree as the
         first patch in that series had to go into stable.  This makes the
         locking much more fine-grained (get rid of the "big GPIO lock(s)"
         and store states in the GPIO descriptors.
    
       - rename gpiod_[g|s]et_array() to gpiod_[g|s]et_array_value() to
         avoid confusions.
    
       - New drivers for:
          * NXP LPC18xx (currently LPC1850)
          * NetLogic XLP
          * Broadcom STB SoC's
          * Axis ETRAXFS
          * Zynq Ultrascale+ (subdriver)
    
       - ACPI:
          * make it possible to retrieve GpioInt resources from a GPIO
            device using acpi_dev_gpio_irq_get()
          * merge some dependent I2C changes exploiting this.
          * support the ARM X-Gene GPIO standby driver.
    
       - make it possible for the generic GPIO driver to read back the value
         set registers to reflect current status.
    
       - loads of OMAP IRQ handling fixes.
    
       - incremental improvements to Kona, max732x, OMAP, MXC, RCAR,
         PCA953x, STP-XWAY, PCF857x, Crystalcove, TB10x.
    
       - janitorial (constification, checkpatch cleanups)"
