Subject: [PATCH 09/10] arm64: dts: qcom: ipq8074-hk01: Add dummy supply for QMP USB3 PHY
Date:   Wed, 29 Sep 2021 11:42:52 +0800
Message-Id: <20210929034253.24570-10-shawn.guo@linaro.org>
In-Reply-To: <20210929034253.24570-1-shawn.guo@linaro.org>
References: <20210929034253.24570-1-shawn.guo@linaro.org>
Precedence: bulk

Per QMP PHY bindings schema, 'vdda-phy-supply' and 'vdda-phy-supply' are
required for IPQ8074 QMP USB3 PHY.  Since supplies are not added in DTS
for this platform, add a dummy regulator as the supply to QMP USB3 PHY,
so that dtbs_check stops complaining the missing supplies.
