1*c66ec88fSEmmanuel VadotGPIO driver for MAX77620 Power management IC from Maxim Semiconductor. 2*c66ec88fSEmmanuel Vadot 3*c66ec88fSEmmanuel VadotDevice has 8 GPIO pins which can be configured as GPIO as well as the 4*c66ec88fSEmmanuel Vadotspecial IO functions. 5*c66ec88fSEmmanuel Vadot 6*c66ec88fSEmmanuel VadotRequired properties: 7*c66ec88fSEmmanuel Vadot------------------- 8*c66ec88fSEmmanuel Vadot- gpio-controller : Marks the device node as a gpio controller. 9*c66ec88fSEmmanuel Vadot- #gpio-cells : Should be two. The first cell is the pin number and 10*c66ec88fSEmmanuel Vadot the second cell is used to specify the gpio polarity: 11*c66ec88fSEmmanuel Vadot 0 = active high 12*c66ec88fSEmmanuel Vadot 1 = active low 13*c66ec88fSEmmanuel VadotFor more details, please refer generic GPIO DT binding document 14*c66ec88fSEmmanuel Vadot<devicetree/bindings/gpio/gpio.txt>. 15*c66ec88fSEmmanuel Vadot 16*c66ec88fSEmmanuel VadotExample: 17*c66ec88fSEmmanuel Vadot-------- 18*c66ec88fSEmmanuel Vadot#include <dt-bindings/mfd/max77620.h> 19*c66ec88fSEmmanuel Vadot... 20*c66ec88fSEmmanuel Vadotmax77620@3c { 21*c66ec88fSEmmanuel Vadot compatible = "maxim,max77620"; 22*c66ec88fSEmmanuel Vadot 23*c66ec88fSEmmanuel Vadot gpio-controller; 24*c66ec88fSEmmanuel Vadot #gpio-cells = <2>; 25*c66ec88fSEmmanuel Vadot}; 26
