Linus Torvalds 980f3c344f 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.

Merge tag 'gpio-v3.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

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
