The commit c329e5afb42f ("net: phy: at803x: select correct page on
config init") selects the copper page during probe. This fails if the
copper page was already selected. In this case, the value of the copper
page (which is 1) is propagated through phy_restore_page() and is
finally returned for at803x_probe(). Fix it, by just using the
at803x_page_write() directly.
Also in case of an error, the regulator is not disabled and leads to a
WARN_ON() when the probe fails. This couldn't happen before, because
at803x_parse_dt() was the last call in at803x_probe(). It is hard to
see, that the parse_dt() actually enables the regulator. Thus move the
regulator_enable() to the probe function and undo it in case of an
error.

Register 27_6.15:14 has the following description in 88E6393X
documentation:
Temperature Sensor Enable
0x0 - Sample every 1s
0x1 - Sense rate decided by bits 10:8 of this register
0x2 - Use 26_6.5 (One shot Temperature Sample) to enable
0x3 - Disable
This is compatible with how the 6390 code uses this register currently,
but the 6390 code handles it as two 1-bit registers (somewhat), instead
of one register with 4 possible values.
(A newer version of the 6390 documentation removed temperature sensor
section completely. In an older version, the above mentioned register
is reserved, although it is R/W. Since the code works, I think we can
assume that it is correct.)
Rename this register and define all 4 values according to 6393X
documentation.

The Atheros AR8031 and AR8033 expose different registers for SGMII/Fiber
as well as the copper side of the PHY depending on the BT_BX_REG_SEL bit
in the chip configure register.
The driver assumes the copper side is selected on probe, but this might
not be the case depending which page was last selected by the
bootloader. Notably, Ubiquiti UniFi bootloaders show this behavior.
Select the copper page when probing to circumvent this.

Setting 10G without autonegotiation is invalid according to
phy_ethtool_ksettings_set(). Thus, we need to set it during
autonegotiation.
If 1G autonegotiation can't complete for quite a time, but there is
signal in line, switch line interface type to 10GBase-R, if supported,
in hope for link to be established.
And vice versa. If 10GBase-R link can't be established for quite a time,
and autonegotiation is enabled, and there is signal in line, switch line
interface type to appropriate 1G mode, i.e. 1000Base-X or SGMII, if
supported.

Since commit fee2d546414d ("net: phy: marvell: mv88e6390 temperature
sensor reading"), Linux reports the temperature of Topaz hwmon as
constant -75°C.
This is because switches from the Topaz family (88E6141 / 88E6341) have
the address of the temperature sensor register different from Peridot.
This address is instead compatible with 88E1510 PHYs, as was used for
Topaz before the above mentioned commit.
Create a new mapping table between switch family and PHY ID for families
which don't have a model number. And define PHY IDs for Topaz and Peridot
families.
Create a new PHY ID and a new PHY driver for Topaz's internal PHY.
The only difference from Peridot's PHY driver is the HWMON probing
method.
Prior this change Topaz's internal PHY is detected by kernel as:
PHY [...] driver [Marvell 88E6390] (irq=63)
And afterwards as:
PHY [...] driver [Marvell 88E6341 Family] (irq=63)

The new netlink API for reading SFP data requires a new op to be
implemented. The idea of the new netlink SFP code is that userspace is
responsible to parsing the EEPROM data and requesting pages, rather
than have the kernel decide what pages are interesting and returning
them. This allows greater flexibility for newer formats.
Currently the generic SFP code only supports simple SFPs. Allow i2c
address 0x50 and 0x51 to be accessed with page and bank must always be
0. This interface will later be extended when for example QSFP support
is added.

Resume callback of the PHY driver is called after the one for the MAC
driver. The PHY driver resume callback calls phy_init_hw(), and this is
potentially problematic if the MAC driver calls phy_start() in its resume
callback. One issue was reported with the fec driver and a KSZ8081 PHY
which seems to become unstable if a soft reset is triggered during aneg.
The new flag allows MAC drivers to indicate that they take care of
suspending/resuming the PHY. Then the MAC PM callbacks can handle
any dependency between MAC and PHY PM.

Here is what Vladimir says about it:
at803x_aneg_done() keeps the aneg reporting as "not done" even when
the copper-side link was reported as up, but the in-band autoneg has
not finished.
That was the _intended_ behavior when that code was introduced, and
Heiner have said about it [1]:
| That's not nice from the PHY:
| It signals "link up", and if the system asks the PHY for link details,
| then it sheepishly says "well, link is *almost* up".
If the specification of phy_aneg_done behavior does not include
in-band autoneg (and it doesn't), then this piece of code does not
belong here.
The fact that we can no longer trigger this code from phylib is yet
another reason why it fails at its intended (and wrong) purpose and
should be removed.
Removing the SGMII link check, would just keep the call to
genphy_aneg_done(), which is also the fallback. Thus we can just remove
at803x_aneg_done() altogether.
