Subject: [PATCH v5 06/12] dt-bindings: power: supply: smb347-charger: Document USB VBUS regulator
Date: Sat, 17 Jul 2021 21:21:28 +0300 [thread overview]
Message-ID: <20210717182134.30262-7-digetx@gmail.com> (raw)
In-Reply-To: <20210717182134.30262-1-digetx@gmail.com>
SMB347 can supply power to USB VBUS, which is required by OTG-cable
devices that want to switch USB port into the host mode. Add USB VBUS
regulator properties.
