    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>;
