This patch series adds the relevant phy and controller DT configurations for enabling PCI gen2 support on IPQ5018. IPQ5018 has two phys and two controllers, one dual-lane and one single-lane. Last patch series (v3) submitted dates back to August 30, 2024. As I've worked to add IPQ5018 platform support in OpenWrt, I'm continuing the efforts to add Linux kernel support.
