    Pull GPIO updates from Linus Walleij:
     "This is the bulk of GPIO changes for the v4.13 series.
    
      Some administrativa:
    
      I have a slew of 8250 serial patches and the new IOT2040 serial+GPIO
      driver coming in through this tree, along with a whole bunch of Exar
      8250 fixes. These are ACKed by Greg and also hit drivers/platform/*
      where they are ACKed by Andy Shevchenko.
    
      Speaking about drivers/platform/* there is also a bunch of ACPI stuff
      coming through that route, again ACKed by Andy.
    
      The MCP23S08 changes are coming in here as well. You already have the
      commits in your tree, so this is just a result of sharing an immutable
      branch between pin control and GPIO.
    
      Core:
       - Export add/remove for lookup tables so that modules can export GPIO
         descriptor tables.
       - Handle GPIO sleep states: it is now possible to flag that a GPIO
         line may loose its state during suspend/resume of the system to
         save power. This is used in the Wolfson Micro Arizona driver.
       - ACPI-based GPIO was tightened up a lot around the edges.
       - Use bitmap_fill() to speed up a loop.
    
      New drivers:
       - Exar XRA1403 SPI-based GPIO.
       - MVEBU driver now supports Armada 7K and 8K.
       - LP87565 PMIC GPIO.
       - Renesas R-CAR R8A7743 (RZ/G1M).
       - The new IOT2040 8250 serial/GPIO also comes in through this
         changeset.
    
      Substantial driver changes:
       - Seriously fix the Exar 8250 GPIO portions to work.
       - The MCP23S08 was moved out to a pin control driver.
       - Convert MEVEBU to use regmap for register access.
       - Drop Vulcan support from the Broadcom driver.
       - Serious cleanup and improvement of the mockup driver, giving us a
         better test coverage.
    
      Misc:
       - Lots of janitorial clean up.
       - A bunch of documentation fixes"
