Subject: [PATCH v2 7/7] arm64: dts: qcom: qcs404: Add PCIe related nodes
Date: Mon, 18 Feb 2019 22:04:07 -0800 [thread overview]
Message-ID: <20190219060407.15263-8-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20190219060407.15263-1-bjorn.andersson@linaro.org>
The QCS404 has a PCIe2 PHY and a Qualcomm PCIe controller, add these to
the platform dtsi and enable them for the EVB with the perst gpio
and analog supplies defined.
