The secondary USB controller is made "host", as it is a Type-A port. Secondary USB controller of QCS615 Ride has Type-A port exposed for connecting peripheral. The VBUS to the peripheral is provided by TPS2549IRTERQ1 regulator connected to the port. The regulator has an enable pin controlled by PM8150. Model it as fixed regulator and keep it Always-On at boot, since the regulator is GPIO controlled regulator.
