Hi,
In the customer's USB design, the VBUS is not connected to the VBUS of the PMIC chip. Is it possible skip the VBUS detection in the driver? If yes, how should it be configured and modified? Below screenshot from TRM.
Figure 24-149 shows typical application of the USB1 controller in USB2.0 device mode. VBUS sensing is
exported to the companion PMIC. USB driver monitors VBUS status by listening to the PMIC interrupts
and using the I2C1 (PMIC control) interface.
