The patch addresses an issue with the reset logic on the i.MX93 SoC, which
requires configuration of the correct interface speed under RMII mode to
complete the reset. The patch implements a fix_soc_reset function and uses
it specifically for the i.MX93 SoCs.

This patch adds support for platform-specific reset logic in the
stmmac driver. Some SoCs require a different reset mechanism than
the standard dwmac IP reset. To support these platforms, a new function
pointer 'fix_soc_reset' is added to the plat_stmmacenet_data structure.
The stmmac_reset in hwif.h is modified to call the 'fix_soc_reset'
function if it exists. This enables the driver to use the platform-specific
reset logic when necessary.

There's no need for "#address-cells/#size-cells" in the brcm,sf2 node as
no immediate child nodes have an address. What was probably intended was
to put them in the 'ports' node, but that's not necessary as that is
covered by ethernet-switch.yaml via dsa.yaml.

The schema doesn't allow for a single (unaddressed) ethernet port node
nor does a single port switch make much sense. So if there's always
multiple child nodes, "#address-cells" and "#size-cells" should be

Announce that the driver supports CAN_CTRLMODE_BERR_REPORTING by means
of priv->can.ctrlmode_supported. Until now berr reporting always has
been active without taking care of the berr-reporting parameter given
to an "ip link set ..." command.
Additionally apply some changes to function esd_usb_rx_event():
- If berr reporting is off and it is also no state change, then
immediately return.
- Unconditionally (even in case of the above "immediate return") store
tx- and rx-error counters, so directly use priv->bec.txerr and
priv->bec.rxerr instead of intermediate variables.
- Not directly related, but to better point out the linkage between a
failed alloc_can_err_skb() and stats->rx_dropped++:
Move the increment of the rx_dropped statistic counter (back) to
directly behind the err_skb allocation.

Refresh the expiration time of a filter each time it's used. Then check

When sending a PTP event packet, add the correct filters that will make
that future incoming unicast PTP event packets will be timestamped.
The unicast address for the filter is gotten from the outgoing skb
before sending it.
Until now they were not timestamped because only filters that match with
the PTP multicast addressed were being configured into the NIC for the
PTP special channel. Packets received through different channels are not
timestamped, getting "received SYNC without timestamp" error in ptp4l.
Note that the inserted filters are never removed unless the NIC is stopped
or reconfigured, so efx_ptp_stop is called. Removal of old filters will
be handled by the next patch.
Additionally, cleanup a bit efx_ptp_xmit_skb_mc to use the reverse xmas
tree convention and remove an unnecessary assignment to rc variable in
void function.

Add a second list for unicast filters and generalize the
efx_ptp_insert/remove_filters functions to allow acting in any of the 2
lists.
No filters for unicast are inserted yet. That will be done in the next
patch.
The reason to use 2 different lists instead of a single one is that, in
next patches, we will want to check if unicast filters are already added
and if they're expired. We don't need that for multicast filters.

Instead of using a fixed sized array for the PTP filters, use a list.
This is not actually necessary at this point because the filters for
multicast PTP are a fixed number, but this is a preparation for the
following patches adding support for unicast PTP.
To avoid confusion with the new struct type efx_ptp_rxfilter, change the
name of some local variables from rxfilter to spec, given they're of the
type efx_filter_spec.

This kind of H2C/C2H must be paired. To identify if any H2C/C2H is missing,
update counters to help diagnose this kind of problems.

Add driver for the built-in Gigabit Ethernet switch which can be found
in the MediaTek MT7988 SoC.
The switch shares most of its design with MT7530 and MT7531, but has
it's registers mapped into the SoCs register space rather than being
connected externally or internally via MDIO.
Introduce a new platform driver to support that.

As MT7530 and MT7531 internally use 32-bit wide registers, each access
to any register of the switch requires several operations on the MDIO
bus. Hence if there is congruent access, e.g. due to PCS or PHY
polling, this can mess up and interfere with another ongoing register
access sequence.
However, the MDIO bus mutex is only relevant for MDIO-connected
switches. Prepare switches which have there registers directly mapped
into the SoCs register space via MMIO which do not require such
locking. There we can simply use regmap's default locking mechanism.
Hence guard mutex operations to only be performed in case of MDIO
connected switches.

Move MDIO-specific functions to newly introduced mt7530-mdio.c while

As the MDIO bus lock only needs to be involved if actually operating
on an MDIO-connected switch we will need to skip locking for built-in

This adds support for the EDPD PHY tunable.
Per default EDPD is disabled in interrupt mode, the tunable can be used
to override this, e.g. if the link partner doesn't use EDPD.
The interval to check for energy can be chosen between 1000ms and
2000ms. Note that this value consists of the 1000ms phylib interval
for state machine runs plus the time to wait for energy being detected.
v2:
- consider that phylib core holds phydev->lock when calling the
phy tunable hooks
