In v5, I modified dt bindings (patch 1) to add descriptions and separate conditions for ipq5018 and ipq5332 as they have different nr of clocks and resets but left your tag in there. I removed it in v6 to run the changes past you again. I intend to send the next version with comments addressed in patch 5 (to add a comment above the max-link-speed property).

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.
