| * 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>;
| };
