The multiport USB controller in the SA8295P ADP is connected to four USB Type-A ports. VBUS for each of these ports are provided by a TPS2559QWDRCTQ1 regulator, controlled from PMIC GPIOs. Add the necessary regulators and GPIO configuration to power these. It seems reasonable that these regulators should be referenced as vbus supply of usb-a-connector nodes and controlled by e.g. dwc3, but as this is not supported in Linux today the regulators are left always-on for now.
