This patch makes functions that were provided for aqr107 applicable to
aqr105, or replaces generic functions with specific ones. Since the aqr105
was introduced before NBASE-T was defined (or 802.3bz), there are a number
of vendor specific registers involved in the definition of the
advertisement, in auto-negotiation and in the setting of the speed. The
functions have been written following the downstream driver for TN4010
cards with aqr105 PHY, and use code from aqr107 functions wherever it
seemed to make sense.

This patch will allow to use a swnode/fwnode defined for a phy_device. The
MDIO bus (mii_bus) needs to contain nodes for the PHY devices, named
"ethernet-phy@i", with i being the MDIO address (0 .. PHY_MAX_ADDR - 1).
The fwnode is only attached to the phy_device if there isn't already an
fwnode attached.
fwnode_get_named_child_node will increase the usage counter of the fwnode.
However, no new code is needed to decrease the counter again, since this is
already implemented in the phy_device_release function.

The SFP module's eeprom and internals are accessible through an i2c bus.
It is possible that the SFP might be connected to an SMBus-only
controller, such as the one found in some PHY devices in the VSC85xx
family.
Introduce a set of sfp read/write ops that are going to be used if the
i2c bus is only capable of doing smbus byte accesses.
As Single-byte SMBus transaction go against SFF-8472 and breaks the
atomicity for diagnostics data access, hwmon is disabled in the case
of SMBus access.
Moreover, as this may cause other instabilities, print a warning at
probe time to indicate that the setup may be unreliable because of the
hardware design.
As hwmon may be disabled for both broken EEPROM and smbus, the warnings
are udpated accordingly.

When the system is suspended, the PHY may be placed in low-power mode
by setting the BMCR 0.11 Power down bit. IEEE 802.3 states that the
behaviour of the PHY in this state is implementation specific, and
the PHY is not required to meet the RX_CLK and TX_CLK requirements.
Essentially, this means that a PHY may stop the clocks that it is
generating while in power down state.
However, MACs exist which require the clocks from the PHY to be running
in order to properly resume. phylink_prepare_resume() provides them
with a way to clear the Power down bit early.
Note, however, that IEEE 802.3 gives PHYs up to 500ms grace before the
transmit and receive clocks meet the requirements after clearing the
power down bit.
Add a resume preparation function, which will ensure that the receive
clock from the PHY is appropriately configured while resuming.

The net fixed phy driver does not require the creation of a platform
device. Originally, this approach was chosen for simplicity when the
driver was first implemented.
With the introduction of the lightweight faux device interface, we now
have a more appropriate alternative. Migrate the device to utilize the
faux bus, given that the platform device it previously created was not
a real one anyway. This will get rid of the fake platform device.

Commit 809265fe96fe ("net: phy: c45: remove local advertisement
parameter from genphy_c45_eee_is_active") stopped reading the local
advertisement from the PHY earlier in this development cycle, which
broke "ethtool --set-eee ethX eee off".
When ethtool is used to set EEE off, genphy_c45_eee_is_active()
indicates that EEE was active if the link partner reported an
advertisement, which causes phylib to set phydev->enable_tx_lpi on
link up, despite our local advertisement in hardware being empty.
However, phydev->advertising_eee is preserved while EEE is turned off,
which leads to genphy_c45_eee_is_active() incorrectly reporting that
EEE is active.
Fix it by checking phydev->eee_cfg.eee_enabled, and if clear,
immediately indicate that EEE is not active.

Introduce an internal phylink helper phylink_caps_to_link_caps() to

to do the link_caps -> linkmodes conversion.

phylink allows MAC drivers to report the capabilities in terms of speed,
duplex and pause support. This is done through a dedicated set of enum
values in the form of the MAC_ capabilities. They are very close to what
the LINK_CAPA_xxx can express, with the difference that LINK_CAPA don't
have any information about Pause/Asym Pause support.
To prepare converting phylink to using the phy_caps, add the mapping
between MAC capabilities and phy_caps. While doing so, we move the
phylink_caps_params array up a bit to simplify future commits.

When phylink creates a fixed-link configuration, it finds a matching
linkmode to set as the advertised, lp_advertising and supported modes
based on the speed and duplex of the fixed link.
Use the newly introduced phy_caps_lookup to get these modes instead of
phy_lookup_settings(). This has the side effect that the matched
settings and configured linkmodes may now contain several linkmodes (the
intersection of supported linkmodes from the phylink settings and the
linkmodes that match speed/duplex) instead of the one from
phy_lookup_settings().

As the link_caps array is efficient for <speed,duplex> lookups,
implement a function for speed/duplex lookups that matches a given
mask. This replicates to some extent the phy_lookup_settings()
behaviour, matching full link_capabilities instead of a single linkmode.
phy.c's phy_santize_settings() and phylink's
phylink_ethtool_ksettings_set() performs such lookup using the
phy_settings table, but are only interested in the actual speed/duplex
that were matched, rathet than the individual linkmode.
Similar to phy_lookup_settings(), the newly introduced phy_caps_lookup()
will run through the link_caps[] array by descending speed/duplex order.
If the link_capabilities for a given <speed/duplex> tuple intersects the
passed linkmodes, we consider that a match.
Similar to phy_lookup_settings(), we also allow passing an 'exact'
boolean, allowing non-exact match. Here, we MUST always match the
linkmodes mask, but we allow matching on lower speed settings.

The canonical definition for all the link modes is in linux/ethtool.h,
which is complemented by the link_mode_params array stored in
net/ethtool/common.h . That array contains all the metadata about each
of these modes, including the Speed and Duplex information.
Phylib and phylink needs that information as well for internal
management of the link, which was done by duplicating that information
in locally-stored arrays and lookup functions. This makes it easy for
developpers adding new modes to forget modifying phylib and phylink
accordingly.
However, the link_mode_params array in net/ethtool/common.c is fairly
inefficient to search through, as it isn't sorted in any manner. Phylib
and phylink perform a lot of lookup operations, mostly to filter modes
by speed and/or duplex.
We therefore introduce the link_caps private array in phy_caps.c, that
indexes linkmodes in a more efficient manner. Each element associated a
tuple <speed, duplex> to a bitfield of all the linkmodes runs at these
speed/duplex.
We end-up with an array that's fairly short, easily addressable and that
it optimised for the typical use-cases of phylib/phylink.
That array is initialized at the same time as phylib. As the
link_mode_params array is part of the net stack, which phylink depends
on, it should always be accessible from phylib.

TJA1120B/TJA1121B can achieve a stable operation of SGMII after
a startup event by putting the SGMII PCS into power down mode and
restart afterwards.
It is necessary to put the SGMII PCS into power down mode and back up.

The most recent sillicon versions of TJA1120 and TJA1121 can achieve
full silicon performance by putting the PHY in managed mode.
It is necessary to apply these PHY writes before link gets established.
Application of this fix is required after restart of device and wakeup
from sleep.

Due to pin strapping the PHY maybe disabled per default. TJA1102 devices
can be enabled by setting the PHY_EN bit. Support is provided for TJA1102S
devices but can be easily added for TJA1102 too.

phylink_init_eee() is currently unused.
It was last added in 2019 by
commit 86e58135bc4a ("net: phylink: add phylink_init_eee() helper")
but it didn't actually wire a use up.
It had previous been removed in 2017 by
commit 939eae25d9a5 ("phylink: remove phylink_init_eee()").
Remove it again.

Move definition of struct phy_package_shared to phy_package.c, and
move remaining PHY package related declarations from phy.h to
phylib.h, thus making them accessible for PHY drivers only.

While doing so remove locked versions phy_package_read() and
