    Pull GPIO updates from Linus Walleij:
     "This is the bulk of the GPIO changes for the v4.14 cycle.
      Not so much changes this time, phew. David Daney and Bartosz
      Golaszewski did all the really interesting work in infrastructure
      improvement across GPIO and IRQ core, hats off for them and to tglx
      and Marc Z for general help with these patch sets.
      Core changes:
       - Allow the GPIO irqchip to allocate IRQs dynamically. This is an
         important change on systems where only a restricted number of IRQs,
         lesser than the number of GPIO lines, can be utilized. Now we can
         allocate these on a first-come-first-served basis instead of
         hogging up valuable IRQ lines.
       - Serious fix-up of the kerneldoc documentation and inclusion into
         the kerneldoc builds.
       - Pulled in the IRQ simulator from the IRQ core tree and use this in
         the GPIO mockup driver for exhaustive testing of interrupt
      New drivers:
       - New driver for ThunderX and OCTEON-TX. This is especially
         interesting as it picks up improvements from the IRQ core that
         allow us to handle fasteoi ACKs upwards in a hierarchy when there
         are IRQ flag latches on several levels in a hierarchy. Very
         interesting work here.
       - New subdriver for Renesas R-Car r8a7745 (RZ/G1E).
       - Several fixes and improvements for Xilinx Zynq GPIO.
       - Support an enablement GPIO for the 74x164 GPIO.
       - Switch a bunch of chips to use devres to allocate irq descriptors.
       - A bunch of constification fixes"
