Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull "ARM: device tree work" from Arnd Bergmann:
 "Most of these patches convert code from using static platform data to
  describing the hardware in the device tree.  This is only the first
  half of the changes for v3.4 because a lot of patches for this topic
  came in the last week before the merge window.

  Signed-off-by: Arnd Bergmann <arnd@arndb.de>"

Fix up trivial conflicts in arch/arm/mach-vexpress/{Kconfig,core.h}

+* Atmel GPIO controller (PIO)
+
+Required properties:
+- compatible: "atmel,<chip>-gpio", where <chip> is at91rm9200 or at91sam9x5.
+- reg: Should contain GPIO controller registers location and length
+- interrupts: Should be the port interrupt shared by all the pins.
+- #gpio-cells: Should be two.  The first cell is the pin number and
+  the second cell is used to specify optional parameters (currently
+  unused).
+- gpio-controller: Marks the device node as a GPIO controller.
+
+Example:
+        pioA: gpio@fffff200 {
+                compatible = "atmel,at91rm9200-gpio";
+                reg = <0xfffff200 0x100>;
