[net-next: PATCH v2 0/7] ACPI MDIO support for Marvell controllers

Hi,

The second version of the patchset addresses all comments received
during v1 review and introduces a couple of new patches that
were requested.

fwnode_mdiobus_register() helper routine was added and it is used
now by 2 drivers (xgmac_mdio and mvmdio). In the latter a clock
handling was significantly simplified by a switch to
a devm_clk_bulk_get_optional().

Last but not least two additional MAC configuration modes ACPI
desctiption were documented ("managed" and "fixed-link") - they
can be processed by the existing fwnode_ phylink helpers and
comply with the standard _DSD properties and hierarchical
data extension. ACPI Maintainers are therefore added to reviewers' list.

More details can be found in the patches and their commit messages.

As before, the feature was verified with ACPI on MacchiatoBin, CN913x-DB
and Armada 8040 DB (fixed-link handling).
Moreover regression tests were performed (old firmware with updated kernel,
new firmware with old kernel and the operation with DT).

The firmware ACPI description is exposed in the public github branch:
https://github.com/semihalf-wojtas-marcin/edk2-platforms/commits/acpi-mdio-r20210613
There is also MacchiatoBin firmware binary available for testing:

I'm looking forward to the comments or remarks.

Best regards,
Marcin
