| MOXA ART GPIO Controller | |
| Required properties: | |
| - #gpio-cells : Should be 2, The first cell is the pin number, | |
| the second cell is used to specify polarity: | |
| 0 = active high | |
| 1 = active low | |
| - compatible : Must be "moxa,moxart-gpio" | |
| - reg : Should contain registers location and length | |
| Example: | |
| gpio: gpio@98700000 { | |
| gpio-controller; | |
| #gpio-cells = <2>; | |
| compatible = "moxa,moxart-gpio"; | |
| reg = <0x98700000 0xC>; | |
| }; |
