that change is only true if there is a kernel change to change the default path for LNL and directly use sof-ipc4-tplg.

True, I can convert this to draft for now until we have consensus on it?
Since LNL is not released I would try to align with this change, just to make our legacy shorter.

What I meant is that IF you want this change for LNL you need to send a kernel PR... I don't personally feel it's necessary but I am not going to lay on the tracks for a path replacement.

And once all the topology and kernel patches are merged we can merge this document and publish it.

- The standard Linux firmware search path and order is followed. The above table covers the base "/lib/firmware" case. See https://docs.kernel.org/driver-api/firmware/fw_search_path.html for more information.
- The topology folder and filename can be overridden with "tplg_path" and "tplg_filename" `snd_sof_pci` kernel parameters.
