-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>;
-	};
