Subject: [PATCH 4/6] arm64: dts: qcom: qcs404-evb: Describe external VBUS regulator
Date: Wed, 11 Mar 2020 19:15:15 +0000	[thread overview]
Message-ID: <20200311191517.8221-5-bryan.odonoghue@linaro.org> (raw)
In-Reply-To: <20200311191517.8221-1-bryan.odonoghue@linaro.org>

VBUS is supplied by an external regulator controlled by a GPIO pin. This
patch models the regulator as regulator-usb3-vbus.
