+* 74XX MMIO GPIO driver
+
+Required properties:
+- compatible: Should contain one of the following:
+   "ti,741g125": for 741G125 (1-bit Input),
+   "ti,741g174": for 741G74 (1-bit Output),
+   "ti,742g125": for 742G125 (2-bit Input),
+   "ti,7474"   : for 7474 (2-bit Output),
+   "ti,74125"  : for 74125 (4-bit Input),
+   "ti,74175"  : for 74175 (4-bit Output),
+   "ti,74365"  : for 74365 (6-bit Input),
+   "ti,74174"  : for 74174 (6-bit Output),
+   "ti,74244"  : for 74244 (8-bit Input),
+   "ti,74273"  : for 74273 (8-bit Output),
+   "ti,741624" : for 741624 (16-bit Input),
+   "ti,7416374": for 7416374 (16-bit Output).
+- reg: Physical base address and length where IC resides.
+- gpio-controller: Marks the device node as a gpio controller.
+- #gpio-cells: Should be two. The first cell is the pin number and
+   the second cell is used to specify the GPIO polarity:
+    0 = Active High,
+    1 = Active Low.
+
+Example:
+	ctrl: gpio@30008004 {
+		compatible = "ti,74174";
+		reg = <0x30008004 0x1>;
+		gpio-controller;
+		#gpio-cells = <2>;
+	};
