Aquaris-5HD's driver looks new and better

MT6589 has 3 gpio areas?

#define GPIO_BASE                   0xF0005000
#define GPIO1_BASE                  0xF020C000

and gpio ext

#define GPIOEXT_BASE        (0xC000) 			//PMIC GPIO base.

gpio-ranges = <&pio 0 0 231>; ???

[akku1139]

most mtk dt pio have wrong gpio-ranges?
