Subject: [net-next: PATCH v2 0/8] DSA: switch to fwnode_/device_

Hi,

This is a re-spin of the DSA migration to fwnode_/device_ API.
As agreed, the ACPI-specific patches were kept aside for now,
until the MDIOSerialBus is submitted and accepted in the ACPI
Specification.

The patchset addresses all comments from the first version,
mostly related to usage of proper device_ helpers. Also,
as it was suggested, fwnode_dev_node_match() routine
was taken out of the network code and introduced as a generic
one in drivers/base/property.c

The details can be found in the changelog below. Any comments or
remarks will be appreciated.

Each patch was tested on:
* On EspressoBIN
* On SolidRun CN913x CEx7 Eval Board

IMPORTANT NOTE:
This patchset is rebased on top of the one from Russell
(https://lore.kernel.org/all/Ys7RdzGgHbYiPyB1@shell.armlinux.org.uk/),
so a care should be taken, when merging to the net-next tree.

Best regards,
Marcin
