Subject: [net-next: PATCH v4 0/8] DSA: switch to fwnode_/device_

Hi,

After a longer while this is a re-spin of the DSA migration
to fwnode_/device_ API.
It addresses all comments from the previous iteration - the
details are summarized in the changelog section below.
For reference, here is the discussion under v3.
https://lore.kernel.org/netdev/20220727064321.2953971-1-mw@semihalf.com/t/

The ultimate goal of these changes is to prepare the DSA to use ACPI in
future, which works locally on my branches [1][2], however, this part
needs to be handled separately on the lists, as discussed in v1.

The patchset is based and tested on top of
pure net-next/main branch. Each commit was checked on:
* On EspressoBIN
* On SolidRun CN913x CEx7 Eval Board 

Any comments or remarks will be appreciated.

Best regards,
Marcin
