+Required properties:
+- compatible:
+ - "qcom,msm-gpio" for MSM controllers
+- #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
+- interrupts : Specify the TLMM summary interrupt number
+- ngpio : Specify the number of MSM GPIOs
