net/fsl: xgmac_mdio: Preamble suppression and custom MDC frequencies
The first patch removes the docs for a binding that has never been
supported by the driver as far as I can see. This is a bit of a
mystery to me, maybe Freescale/NXP had/has support for it in an
internal version?
We then start working on the xgmac_mdio driver, converting the driver
to exclusively use managed resources, thereby simplifying the error
paths. Suggested by Andrew.
Preamble suppression is then added, followed by MDC frequency
customization. Neither code will change any bits if the corresponding
dt properties are not specified, so as to not trample on any setup
done by the bootloader, which boards might have relied on up to now.
Finally, we document the new bindings.

net: stmmac/xpcs: modernise PCS support
This series updates xpcs and stmmac for the recent changes to phylink
to better support split PCS and to get rid of private MAC validation
functions.
This series is slightly more involved than other conversions as stmmac
has already had optional proper split PCS support.
The first six patches of this series were originally posted on 16th
December for CFT, and Wong Vee Khee reported his Intel Elkhart Lake
setup was fine the first six these. However, no tested-by was given.
The patches:
1) Provide a function to query the xpcs for the interface modes that
are supported.
2) Populates the MAC capabilities and switches stmmac_validate() to use
phylink_get_linkmodes(). We do not use phylink_generic_validate() yet
as (a) we do not always have the supported interfaces populated, and
(b) the existing code does not restrict based on interface. There
should be no functional effect from this patch.
3) Populates phylink's supported interfaces from the xpcs when the xpcs
is configured by firmware and also the firmware configured interface
mode. Note: this will restrict stmmac to only supporting these
interfaces modes - stmmac maintainers need to verify that this
behaviour is acceptable.
4) stmmac_validate() tail-calls xpcs_validate(), but we don't need it to
now that PCS have their own validation method. Convert stmmac and
xpcs to use this method instead.
5) xpcs sets the poll field of phylink_pcs to true, meaning xpcs
requires its status to be polled. There is no need to also set the
phylink_config.pcs_poll. Remove this.
6) Switch to phylink_generic_validate(). This is probably the most
contravertial change in this patch set as this will cause the MAC to
restrict link modes based on the interface mode. From an inspection
of the xpcs driver, this should be safe, as XPCS only further
restricts the link modes to a subset of these (whether that is
correct or not is not an issue I am addressing here.) For
implementations that do not use xpcs, this is a more open question
and needs feedback from stmmac maintainers.
7) Convert to use mac_select_pcs() rather than phylink_set_pcs() to set
the PCS - the intention is to eventually remove phylink_set_pcs()
once there are no more users of this.

Fill in phylink's supported_interfaces bitmap with the PHY interface

We indicate that the PHY interface mode passed in platform data is
always supported, as this is the initial mode passed into phylink.
When there is no PCS specified, we assume that this is the only mode
that is supported - indeed, the driver appears not to support dynamic
switching of interface types at present.
When a xpcs is present, it defines the PHY interface modes that the
stmmac driver can support. Request the supported interfaces from the
xpcs driver, and pass them to phylink.

We are in the process of qualifying a new system that has RJ45 ports as

missing BaseT link modes and rejecting ethtool operations that are
specific to transceiver modules.
Patchset overview:
Patches #1-#3 are cleanups and preparations.
Patch #4 adds support for two new link modes.
Patches #5-#6 query and cache the port module's type (e.g., QSFP, RJ45)
during initialization.
Patches #7-#9 forbid ethtool operations that are invalid on RJ45 ports.

Transceiver module reset through 'rst' field in PMAOS register is not

type that was queried during initialization and return an error to user
space in case the port module type is RJ45 (twisted pair).
