Add option in enum phy_link_speed to disable auto-negotiation.
This allows PHY drivers to support disabling auto-negotiation.

make sure that autonegotiation is restarted, after
changing the speeds. Also make sure to only write
the changed registers, as mdio is pretty slow.

rename LINK_*_*BASE_T to LINK_*_*BASE
speed options for ethernet drivers shouldn't end with a _T, implying
that ethernet is only supported via a twisted pair cable.

Looping while waiting for auto-negotiation to complete can block the

The ICS1894 phy AN_COMPLETE bit is latched high, this make the
BMSR first read return incorrect status of the AN state, update
one more BMSR read to ensure all latched bit is clear and BMSR
return actual status of the phy chip

the dts binding of the ethernet-phy has the option
"no-reset" and the according driver already has the
right logic to make use of it, but unfortunately
the connection between them was missing.

In fixed-link mode, mdio remains unconfigured. This results in a null

Updates Ethernet PHY devicetree bindings to be more consistent with
Linux by using the standard `reg` property for the PHY address instead
of a custom `address` property. As a result, MDIO controller bindings
now require standard `#address-cells` and `#size-cells` properties.

Just use dev->name. This change follow same principles applied when

A common pattern here was to take the work item as the subfield of a
containing object. But the contained field is not a k_work, it's a
k_work_delayable.
Things were working only because the work field was first, so the
pointers had the same value. Do things right and fix things to
produce correct code if/when that field ever moves within delayable.

This commit adds support for Ethernet PHY drivers via a PHY API.
It also includes a driver for a generic MII compliant PHY
which supports most PHYs on the market.
Separating PHY driver from the SoC specific Ethernet driver
simplifies the Ethernet driver code and enables code re-use.
Drivers for specific PHYs with more advanced features, such as
RGMII delay in PHY can be developed independent of the Ethernet
MAC driver.
