+Nomadik GPIO controller
+
+Required properties:
+- compatible : Should be "st,nomadik-gpio".
+- reg : Physical base address and length of the controller's registers.
+- interrupts : The interrupt outputs from the controller.
+- #gpio-cells : Should be two:
+ The first cell is the pin number.
+ The second cell is used to specify optional parameters:
+ - bits[3:0] trigger type and level flags:
+ 1 = low-to-high edge triggered.
+ 2 = high-to-low edge triggered.
+ 4 = active high level-sensitive.
+ 8 = active low level-sensitive.
+- gpio-controller : Marks the device node as a GPIO controller.
+- interrupt-controller : Marks the device node as an interrupt controller.
+- gpio-bank : Specifies which bank a controller owns.
+- st,supports-sleepmode : Specifies whether controller can sleep or not
+
+Example:
