-Subject: [PATCH] usb: dwc2: add support for host mode external vbus supply
-
-This patch adds a way to enable an external vbus supply in host mode,
-when dwc2 drvvbus signal is not used.
-
-This patch is very similar to the one done in U-Boot dwc2 driver [1]. It
-also adds dynamic vbus supply management depending on the role and state
-of the core.
