So we had four devicetrees (one is new in 6.0) with incorrect serdes region sizes that included the adjacent regions. I've sent fixes for those now, and I don't think we need to add workarounds for booting older malformed dtbs in this case, at least not until someone complains. We do however have two USB PHY bindings that currently rely on overlapping regions which would require some more work to be fixed up. Specifically, the USB PHY driver uses two separate PCS regions but the binding treats them as one and the driver ends up mapping everything in between. This sort of works on all platforms but two where the TX and RX regions lie in between. The binding and driver should probably be fixed up to define this PCS_USB region explicitly, but that work is left for another day. Meanwhile, I've implemented a workaround that fall back to using non-exclusive mappings for these platforms. I'll send a v2 with this. Finally, note that new sc8280xp USB4/USB3/DP binding is also broken, but that's really a separate issue and we're working on fixing that up. Johan
