Merge tag 'mfd_3.4-1' of git://git.kernel.org/pub/scm/linux/kernel/gi…

…t/sameo/mfd-2.6

Pull MFD changes from Samuel Ortiz:
 - 4 new drivers: Freescale i.MX on-chip Anatop, Ricoh's RC5T583 and
   TI's TPS65090 and TPS65217.
 - New variants support (8420, 8520 ab9540), cleanups and bug fixes for
   the abx500 and db8500 ST-E chipsets.
 - Some minor fixes and update for the wm8994 from Mark.
 - The beginning of a long term TWL cleanup effort coming from the TI
   folks.
 - Various fixes and cleanups for the s5m, TPS659xx, pm860x, and MAX8997
   drivers.

Fix up trivial conflicts due to duplicate patches and header file
cleanups (<linux/device.h> removal etc).

+twl4030 GPIO controller bindings
+
+Required properties:
+- compatible:
+  - "ti,twl4030-gpio" for twl4030 GPIO controller
+- #gpio-cells : Should be two.
+  - first cell is the pin number
+  - second cell is used to specify optional parameters (unused)
+- gpio-controller : Marks the device node as a GPIO controller.
+- #interrupt-cells : Should be 2.
+- interrupt-controller: Mark the device node as an interrupt controller
+  The first cell is the GPIO number.
+  The second cell is not used.
+
+Example:
+
+twl_gpio: gpio {
+    compatible = "ti,twl4030-gpio";
+    #gpio-cells = <2>;
+    gpio-controller;
+    #interrupt-cells = <2>;
