dpaa2_mac_is_type_fixed() is a header with no implementation and no
callers, which is referenced from the documentation though. It can be
deleted.
On the other hand, it would be useful to reuse the code between
dpaa2_eth_is_type_phy() and dpaa2_switch_port_is_type_phy(). That common
code should be called dpaa2_mac_is_type_phy(), so let's create that.
The removal and the addition are merged into the same patch because,
in fact, is_type_phy() is the logical opposite of is_type_fixed().

This patch integrates the dpaa2-eth driver with the generic PHY
infrastructure in order to search, find and reconfigure the SerDes lanes
in case of a protocol change.
On the .mac_config() callback, the phy_set_mode_ext() API is called so
that the Lynx 28G SerDes PHY driver can change the lane's configuration.
In the same phylink callback the MC firmware is called so that it
reconfigures the MAC side to run using the new protocol.
The consumer drivers - dpaa2-eth and dpaa2-switch - are updated to call
the dpaa2_mac_start/stop functions newly added which will
power_on/power_off the associated SerDes lane.

Retrieve the API version running on the firmware and based on it detect
which features are available for usage.
The first one to be listed is the capability to change the MAC protocol
at runtime.

Remove references to lynx_pcs structures so drivers like the Felix DSA
can reference alternate PCS drivers.

Modify dpaa2_mac_get_node() to get the dpmac fwnode from either
DT or ACPI.
Modify dpaa2_mac_get_if_mode() to get interface mode from dpmac_node
which is a fwnode.
Modify dpaa2_pcs_create() to create pcs from dpmac_node fwnode.
Modify dpaa2_mac_connect() to support ACPI along with DT.

When the DPNI object is connected to a DPMAC, setup the of_node to point
to the DTS device node of that specific MAC. This enables other drivers,
for example the DSA subsystem, to find the net_device by its device
node.

Split up the initialization phase of the dpmac object from actually
configuring the phylink instance, connecting to it and configuring the
MAC. This is done so that even though the dpni object is connected to a
dpmac which has link management handled by the firmware we are still
able to export the MAC counters.

Include PCS support in the dpaa2-eth driver by integrating it with the
new Lynx PCS module. There is not much to talk about in terms of changes
needed in the dpaa2-eth driver since the only steps necessary are to
find the MDIO device representing the PCS, register it to the Lynx PCS
module and then let phylink know if its existence also.
After this, the PCS callbacks will be treated directly by Lynx, without
interraction from dpaa2-eth's part.

Convert the DPAA2 ethernet driver to use the finalised link parameters
in mac_link_up() rather than the parameters in mac_config(), which are
more suited to the needs of the DPAA2 MC firmware than those available
via mac_config().

When a DPNI is connected to a MAC, export its associated counters.
Ethtool related functions are added in dpaa2_mac for returning the
number of counters, their strings and also their values.

The dpaa2-eth driver now has support for connecting to its associated
PHY device found through standard OF bindings.
This happens when the DPNI object (that the driver probes on) gets
connected to a DPMAC. When that happens, the device tree is looked up by
the DPMAC ID, and the associated PHY bindings are found.
The old logic of handling the net device's link state by hand still
needs to be kept, as the DPNI can be connected to other devices on the
bus than a DPMAC: other DPNI, DPSW ports, etc. This logic is only
engaged when there is no DPMAC (and therefore no phylink instance)
attached.
The MC firmware support multiple type of DPMAC links: TYPE_FIXED,
TYPE_PHY. The TYPE_FIXED mode does not require any DPMAC management from
Linux side, and as such, the driver will not handle such a DPMAC.
Although PHYLINK typically handles SFP cages and in-band AN modes, for
the moment the driver only supports the RGMII interfaces found on the
LX2160A. Support for other modes will come later.
