| * 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>; |
| }; |
