[PATCH 3/3] ARM: dts: stm32: enable USB OTG Dual Role on stm32mp157c-ev1

From: Amelie Delaunay
Date: Tue Feb 04 2020 - 08:26:33 EST


Now that st,stm32mp15-hsotg is used, dual role is supported. ID pin is
managed to detect the current role.
On stm32mp157c-ev1, Host mode requires a vbus-supply property. Charge pump
for vbus is provided by PMIC VBUS_OTG.
