Actually, no this was my fault for inadvertantly including this patch in
the branch:

http://lore.kernel.org/r/653c7eb29265c_244c8f29...@dwillia2-xfh.jf.intel.com.notmuch

...which had the desired effect, but at the cost of thrashing
linux-next. Apologies for that.

I have no idea about the above (and all the similar ones below); I
assume they all have to do with
https://lore.kernel.org/r/20231018171713.1883517-13-rrich...@amd.com

Safe but annoying.  Yoshihiro, can you fix this by adding structs for
the of_device_id.data member instead of casting DW_PCIE_RC_TYPE and
DW_PCIE_EP_TYPE?  Examples here:

Siddharth, since you're looking at keystone v3.65, it looks to me like
DW_PCIE_VER_365A is currently broken because ks_pcie_rc_of_data
doesn't set .mode, so it defaults to zero, and it looks like we should
end up at the INVALID device type case here:
