This is where I confused, USB-DRVVBUS is connected to pin 51 of PMIC if we add 5v regulator how can configure gpio number for this? I saw sun8i-a33-olinuxino.dts which is also similar but it has gpio = <&pio 1 9 GPIO_ACTIVE_HIGH>; thanks! -- Jagan Teki Free Software Engineer | www.openedev.com U-Boot, Linux | Upstream Maintainer Hyderabad, India.
