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
     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"

+* 74XX MMIO GPIO driver
+
+Required properties:
+- compatible: Should contain one of the following:
+   "ti,741g125": for 741G125 (1-bit Input),
+   "ti,741g174": for 741G74 (1-bit Output),
+   "ti,742g125": for 742G125 (2-bit Input),
+   "ti,7474"   : for 7474 (2-bit Output),
+   "ti,74125"  : for 74125 (4-bit Input),
+   "ti,74175"  : for 74175 (4-bit Output),
+   "ti,74365"  : for 74365 (6-bit Input),
+   "ti,74174"  : for 74174 (6-bit Output),
+   "ti,74244"  : for 74244 (8-bit Input),
+   "ti,74273"  : for 74273 (8-bit Output),
+   "ti,741624" : for 741624 (16-bit Input),
+   "ti,7416374": for 7416374 (16-bit Output).
+- reg: Physical base address and length where IC resides.
+- gpio-controller: Marks the device node as a gpio controller.
+- #gpio-cells: Should be two. The first cell is the pin number and
+   the second cell is used to specify the GPIO polarity:
+    0 = Active High,
+    1 = Active Low.
+
+Example:
+	ctrl: gpio@30008004 {
+		compatible = "ti,74174";
+		reg = <0x30008004 0x1>;
+		gpio-controller;
+		#gpio-cells = <2>;
+	};
