* 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>;
};
