Change the API to select MAC default time stamping instead of the PHY.
Indeed the PHY is closer to the wire therefore theoretically it has less
delay than the MAC timestamping but the reality is different. Due to lower
time stamping clock frequency, latency in the MDIO bus and no PHC hardware
synchronization between different PHY, the PHY PTP is often less precise
than the MAC. The exception is for PHY designed specially for PTP case but
these devices are not very widespread. For not breaking the compatibility
default_timestamp flag has been introduced in phy_device that is set by
the phy driver to know we are using the old API behavior.

In preparation for using the power sequencing subsystem on sm8650 boards
and X13s laptop let's make pwrseq the default for wcn7850 and wcn6855.
Both these models require an enable GPIO so we can safely assume that if
the property is not there, then we should try to get the power
sequencer. Due to how the pwrseq lookup works - checking the provider at
run-time - we cannot really do it the other way around as we'd get stuck
forever on -EPROBE_DEFER.
If the relevant OF node does have the 'enable-gpios' property, we
fallback to the existing code for backward compatibility with older DTs.

schedule a devres action for disabling the SUSCLK rather than doing it

We cannot really use devm_clk_get_enabled() as we also set the rate
before enabling the clock. While this should in theory work, I don't
want to risk breaking existing users. One solution for the future is to
add devm_clk_get_enabled_with_rate() to the clock framework.

net: dsa: vsc73xx: Implement VLAN operations
This patch series is a result of splitting a larger patch series [0],
where some parts was merged before.
The first patch implements port state configuration, which is required
for bridge functionality. STP frames are not forwarded at this moment.
BPDU frames are only forwarded from/to the PI/SI interface.
For more information, see chapter 2.7.1 (CPU Forwarding) in the
datasheet.
Patches 2, 7-9 and 11 provide a basic implementation of tag_8021q
functionality with QinQ support, without VLAN filtering in
the bridge and simple VLAN awareness in VLAN filtering mode.
Patches 3-6 came from Vladimir Oltean. They prepare for making
tag8021q more common. VSC73XX uses very similar tag recognition,
and some code from tag_sja1105 could be moved to tag_8021q for
common use.
Patch 10 is preparation for use tag_8021q bridge functions as generic
implementation of the 'ds->ops->port_bridge_*()'.
Patch 12 is required to avoid problem with learning on standalone ports.

This patch implements .port_pre_bridge_flags() and .port_bridge_flags(),
which are required for properly treating the BR_LEARNING flag. Also,
.port_stp_state_set() is tweaked and now disables learning for standalone
ports.
Disabling learning for standalone ports is required to avoid situations
where one port sees traffic originating from another, which could cause
packet drops.

This patch adds bridge support for the vsc73xx driver.
The vsc73xx requires minimal operations and ithe generic
dsa_tag_8021q_bridge_* API is sufficient.
The forwarding matrix is managed by vsc73xx_port_stp_state_set() ->
vsc73xx_refresh_fwd_map()i routine, which is called immediately after
.port_bridge_join() and .port_bridge_leave().

The 'dsa_tag_8021q_bridge_join' could be used as a generic implementation
of the 'ds->ops->port_bridge_join()' function. However, it is necessary
to synchronize their arguments.
This patch also moves the 'tx_fwd_offload' flag configuration line into
'dsa_tag_8021q_bridge_join' body. Currently, every (sja1105) driver sets
it, and the future vsc73xx implementation will also need it for
simplification.

Max number of bridges in tag8021q implementation is strictly limited
by VBID size: 3 bits. But zero is reserved and only 7 values can be used.
This patch adds define which describe maximum possible value.
