[PATCH v2 3/3] usb: chipidea: otg: not wait vbus drop if use role_switch
From: Xu Yang
Date: Thu Apr 02 2026 - 03:21:17 EST
The usb role switch will update ID and VBUS states at the same time, and
vbus will not drop when execute data role swap in Type-C usecase. So lets
not wait vbus drop in usb role switch case too.
