What you had in your previous examples, just don't call it components
but come up with a new term:

$ devlink dev info
pci/0000:01:00.0:
  driver mlxsw_spectrum2
  versions:
      fixed:
        hw.revision A0
        fw.psid MT_0000000199
      running:
        fw.version 29.2010.2302
        fw 29.2010.2302
  groups? sections? subordinates? :                         <= here
    lc1:
      versions:
        fixed:
          hw.revision 0
          fw.psid MT_0000000111
        running:
          fw 19.2010.1310
          ini.version 4

Note that lc1 is not a nest at netlink level but user space can group
the attrs pretty trivially.

Ah, sorry. I hope the above is clear.

Why would I prototype your feature for you? I prefer a separate dl
instance. If you want to explore other options the "drawing out" is
on you :/
