Subject: [PATCH V4 4/6] arm64: dts: qcom: ipq9574: Add PCIe PHYs and controller nodes
Date:   Fri, 19 May 2023 14:32:17 +0530
Message-ID: <20230519090219.15925-5-quic_devipriy@quicinc.com>
In-Reply-To: <20230519090219.15925-1-quic_devipriy@quicinc.com>

Precedence: bulk

Add PCIe0, PCIe1, PCIe2, PCIe3 (and corresponding PHY) devices
found on IPQ9574 platform. The PCIe0 & PCIe1 are 1-lane Gen3
host whereas PCIe2 & PCIe3 are 2-lane Gen3 host.
