This patch series adds support to the Tehuti tn40xx driver for TN9510 cards
which combine a TN4010 MAC with an Aquantia AQR105.
It is a replacement for the proposed patch series "net: phy: aquantia: enable
firmware loading for aqr105 on PCIe cards" for firmware loading to Aquantia PHYs
from the filesystem, see
https://lore.kernel.org/netdev/[e-mail]/

As suggested by Andrew Lunn, I have replaced the potentially unreliable
firmware-name composition deriving a name from MDIO and phy names with a
more robust method, where the MAC provides a file name via software nodes.

Therefore, this is now a combined patch series adding functionality to the
aquantia PHY driver to read a file name from swnode and to the tn40xx MAC driver
to create the swnode.
Additionally, a few small changes are added to allow firmware loading from the
filesystem for the Aquantia AQR105 phy and loading of the tn40xx driver for the
TN9510 card (TN4010 MAC + AQR105 PHY).

The patch was tested on a Tehuti TN9510 card (1fc9:4025).

Hans-Frieder Vogt (5):
   net: phy: aquantia: add probe function to aqr105 for firmware loading
   net: phy: aquantia: allow firmware loading after aqr_wait_reset_complete
   net: phy: aquantia: search for firmware-name in fwnode
   net: tn40xx: enable driver to support TN4010 cards with AQR105 PHY
   net: tn40xx: register swnode and connect it to the mdiobus
