Subject: [PATCHv2 1/2] dt-bindings: usb: dwc2: add support for STM32MP15 SoCs USB OTG HS and FS
Date: Thu, 16 Jan 2020 15:45:23 +0100 [thread overview]
Message-ID: <20200116144524.16070-2-amelie.delaunay@st.com> (raw)
In-Reply-To: <20200116144524.16070-1-amelie.delaunay@st.com>
Add the specific compatible string for the DWC2 IP found in the STM32MP15
SoCs.
STM32MP15 SoCs uses sensing comparators to detect Vbus valid levels and
ID pin state. usb33d-supply described the regulator supplying Vbus and ID
sensing comparators.
