1* ARM Cirrus Logic CLPS711X SYSFLG1 MCTRL GPIOs 2 3Required properties: 4- compatible: Should contain "cirrus,ep7209-mctrl-gpio". 5- gpio-controller: Marks the device node as a gpio controller. 6- #gpio-cells: Should be two. The first cell is the pin number and 7 the second cell is used to specify the gpio polarity: 8 0 = Active high, 9 1 = Active low. 10 11Example: 12 sysgpio: sysgpio { 13 compatible = "cirrus,ep7312-mctrl-gpio", 14 "cirrus,ep7209-mctrl-gpio"; 15 gpio-controller; 16 #gpio-cells = <2>; 17 }; 18
