Subject: [PATCH 3/3] ARM: dts: stm32: enable USB OTG Dual Role on stm32mp157c-ev1
Date: Tue, 4 Feb 2020 14:26:06 +0100 [thread overview]
Message-ID: <20200204132606.20222-4-amelie.delaunay@st.com> (raw)
In-Reply-To: <20200204132606.20222-1-amelie.delaunay@st.com>
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.
