Subject: [PATCH V5 4/6] arm64: dts: qcom: ipq9574: Add PCIe PHYs and controller nodes
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.
Signed-off-by: devi priya <quic_devipriy@...cinc.com>
---
Changes in V5:
- Dropped anoc and snoc lane clocks from Phy nodes and enabled them
via interconnect.
- Dropped msi-parent as it is handled via msi IRQ
