    Pull take two of the GPIO updates:
     "Same stuff as last time, now with a fixup patch for the previous
      compile error plus I ran a few extra rounds of compile-testing.
    
      This is the bulk of GPIO changes for the v3.19 series:
    
       - A new API that allows setting more than one GPIO at the time.  This
         is implemented for the new descriptor-based API only and makes it
         possible to e.g. toggle a clock and data line at the same time, if
         the hardware can do this with a single register write.  Both
         consumers and drivers need new calls, and the core will fall back
         to driving individual lines where needed.  Implemented for the
         MPC8xxx driver initially
    
       - Patched the mdio-mux-gpio and the serial mctrl driver that drives
         modems to use the new multiple-setting API to set several signals
         simultaneously
    
       - Get rid of the global GPIO descriptor array, and instead allocate
         descriptors dynamically for each GPIO on a certain GPIO chip.  This
         moves us closer to getting rid of the limitation of using the
         global, static GPIO numberspace
    
       - New driver and device tree bindings for 74xx ICs
    
       - New driver and device tree bindings for the VF610 Vybrid
    
       - Support the RCAR r8a7793 and r8a7794
    
       - Guidelines for GPIO device tree bindings trying to get things a bit
         more strict with the advent of combined device properties
    
       - Suspend/resume support for the MVEBU driver
    
       - A slew of minor fixes and improvements"
