    Pull GPIO tree bulk changes from Linus Walleij:
     "A big set this merge window, as we have much going on in this
      subsystem.  The changes to other subsystems (notably a slew of ARM
      machines as I am doing away with their custom APIs) have all been
      ACKed to the extent possible.
    
      Major changes this time:
    
       - Some core improvements and cleanups to the new GPIO descriptor API.
         This seems to be working now so we can start the exodus to this
         API, moving gradually away from the global GPIO numberspace.
    
       - Incremental improvements to the ACPI GPIO core, and move the few
         GPIO ACPI clients we have to the GPIO descriptor API right *now*
         before we go any further.  We actually managed to contain this
         *before* we started to litter the kernel with yet another hackish
         global numberspace for the ACPI GPIOs, which is a big win.
    
       - The RFkill GPIO driver and all platforms using it have been
         migrated to use the GPIO descriptors rather than fixed number
         assignments.  Tegra machine has been migrated as part of this.
    
       - New drivers for MOXA ART, Xtensa GPIO32 and SMSC SCH311x.  Those
         should be really good examples of how I expect a nice GPIO driver
         to look these days.
    
       - Do away with custom GPIO implementations on a major part of the ARM
         machines: ks8695, lpc32xx, mv78xx0.  Make a first step towards the
         same in the horribly convoluted Samsung S3C include forest.  We
         expect to continue to clean this up as we move forward.
    
       - Flag GPIO lines used for IRQ on adnp, bcm-kona, em, intel-mid and
         lynxpoint.
    
         This makes the GPIOlib core aware that a certain GPIO line is used
         for IRQs and can then enforce some semantics such as disallowing a
         GPIO line marked as in use for IRQ to be switched to output mode.
    
       - Drop all use of irq_set_chip_and_handler_name().  The name provided
         in these cases were just unhelpful tags like "mux" or "demux".
    
       - Extend the MCP23s08 driver to handle interrupts.
    
       - Minor incremental improvements for rcar, lynxpoint, em 74x164 and
         msm drivers.
    
       - Some non-urgent bug fixes here and there, duplicate #includes and
         that usual kind of cleanups"
    
    Fix up broken Kconfig file manually to make this all compile.
