Subject: [PATCH v3 5/6] arm64: dts: qcom: ipq5018: Add PCIe related nodes
From: Sricharan Ramabadhran <quic_srichara@...cinc.com>
From: Nitheesh Sekar <quic_nsekar@...cinc.com>
Add phy and controller nodes for a 2-lane Gen2 and
a 1-lane Gen2 PCIe bus. IPQ5018 has 8 MSI SPI interrupts and
one global interrupt.
