net: designware: look for a child device node for MDIO bus ...

The Designware driver registers a local MDIO bus for each MAC device,
but without setting a device node pointer for the MDIO bus device.  In
this case, mdiobus_register() will use the MDIO bus's parent device node
(if any) as the MDIO device node.

If the MAC device node has a child node compatible with
"snps,dwmac-mdio", let us use that as the MDIO bus device node.
Otherwise, leave the MDIO bus device node pointer set to NULL and carry
on as before.

The upshot is that PHY device nodes can now be placed in an intermediate
node for the MDIO bus instead of having to place them directly in the
Designware MAC device node.

(Tested on a Terasic DE0-Nano-SoC with a suitably modified device tree.)

net: phy: mv88e6xxx: Add support for MAC ports ...

Add support for MAC-only/no-PHY ports by adding code that will create
a pseudo PHY device for such ports and a driver to match
against. Original Linux driver exposes all of the ports using DSA
subystem, but lacking that in Barebox, creating pseudo PHYs is the
simplest option to have code to properly configure various interface
parameters.

This is needed, for example, on ZII RPU2 board where FEC is connected
directly to one of the MAC-only ports. That link requires proper RGMII
delay configuration in order to be functional.

mdio_bus: Allow for non PHY-devices on MDIO buses ...

Instead of just creating a simple PHY device for every child of MDIO
bus node, add code to check if any of them have "compatible" property
set, as well as code to create a proper platform device for such
cases.

This change is useful for when MDIO bus and some of Ethernet ports are
connected to a switch or some other MDIO device that doesn't behave
like a generic PHY and can't be probed via its PHY ID.

net: phy: Check phy_mask in get_phy_device() ...

Do not try to probe PHY devices if they are masked in phy_mask. This

default. With this change it still remains possible to add such a
device explicitly either using "miitool" or calling
phy_device_create() explicilty.

phy: call adjust_link in attach if using fixed-link ...

Normally, phy_update_status is in charge of reporting a change in link
status when phy is updated. When using fixed-link, speed and duplex are
initialized directly after registering the phy and there is no driver.
Hence when phy_update_status is called, the check for new values fails
and returns directly. Since update_link call is mandatory for some
network devices to work, call it directly when using fixed link in
phy_device_attach to force update of link.
