+ST-Ericsson COH 901 571/3 GPIO controller
+
+Required properties:
+- compatible: Compatible property value should be "stericsson,gpio-coh901"
+- reg: Physical base address of the controller and length of memory mapped
+ region.
+- interrupts: the 0...n interrupts assigned to the different GPIO ports/banks.
