In commit <a058052c358c> [net: phy: do not read configuration register on
reset], phy_reset() will clear the BMCR register. Bit 12(AUTO_NEGOTIATION)
is cleared too. It causes auto-negotiation timeout error on Atheros's
PHY AR8033.
To fix this problem, genphy_config_aneg() and genphy_restart_aneg()
needs to be called in ar8035_config() to enable and restart
auto-negotiation.

With commit a058052c [net: phy: do not read configuration register on
reset], phy_reset() will clear the BMCR register. Resulting in bit 12
being cleared (A/N enable). This leads to autonegotiation link problems,
at least on the Marvell Armada ClearFog board. I suspect that other
boards using this driver will be affected as well.
At the of m88e1111s_config(), phy_reset() is called. This is not needed
for the PHY to load the changed configuration, as phy_reset() is called
a few lines before already. So lets call genphy_restart_aneg() here
instead to start the AN correctly.
Tested on clearfog.

The picoseconds to register value divisor(ps_to_regval) should be 60 and not
200. Linux has KSZ9031_PS_TO_REG defined to be 60 as well. 60 is the correct
divisor because the 4-bit skew values are defined from 0x0000(-420ps) to
0xffff(480ps), increments of 60.
For example, a DTS skew value of 420, represents 0ps delay, which should be 0x7.
With the previous divisor of 200, it would result in 0x2, which represents a
-300ps delay.
With this patch, ethernet on the SoCFPGA DE0 Atlas is now able to work with
1Gb ethernet.

When configuring a PHY in fixed (forced) link mode, in order for
the changes to be applied, either one of these conditions must
be triggered:
1- PHY is reset
2- Autoneg is restarted
3- PHY transitions from power-down to power-up
Neither of these is currently done, so effectively the fixed link
configuration is not applied in the PHY.
Fix this by setting the Autoneg restart bit.

Micrel PHYs KSZ8021/31 and KSZ8081 have a feature where MDIO address 0
is considered as a broadcast address; the PHY will respond even if it
is not its configured (pinstrapped) address. This feature is enabled
by default.
The Linux kernel disables that feature at initialisation, but not
before it probes the MDIO bus. This causes an issue, because a PHY
at address 3 will be discovered at addresses 0 and 3, but will then
only respond at address 3. Because Linux attaches the first PHY it
discovers on 'eth0', it will attach the PHY from address 0, which
will never answer again.
Fix the issue by disabling the broadcast feature in U-Boot, before
Linux is started.

There are situations when phy may handle faster modes than the

That works fine if GMAC has just exited reset state but we may as well
change connection mode in runtime. Then we'll need to reprogram GMAC for
that new mode of operation and if previous mode was 10 or 100 Mb and new
one is 1 Gb we'll need to reset port mode bit.

of_set_phy_supported allows overwiting hardware capabilities of
a phy with values from the devicetree. This does not work with
the genphy driver though because the genphys config_init function
will overwrite all values adjusted by of_set_phy_supported. Fix
this by initialising the genphy features in the phy_driver struct
and in config_init just limit the features to the ones the hardware
can actually support. The resulting features are a subset of the
devicetree specified features and the hardware features.

When a Gigabit PHY device is connected to a 10/100Mbits capable Ethernet
MAC, the driver will restrict the phydev->supported modes to mask off
Gigabit. If the Gigabit PHY comes out of reset with the Gigabit features
set by default in MII_CTRL1000, it will keep advertising these feature,
so by the time we call genphy_config_advert(), the condition on
phydev->supported having the Gigabit features on is false, and we do not
update MII_CTRL1000 with updated values, and we keep advertising Gigabit
features, eventually configuring the PHY for Gigabit whilst the Ethernet
MAC does not support that.
This patches fixes the problem by ensuring that the Gigabit feature bits
are always cleared in MII_CTRL1000, if the PHY happens to be a Gigabit
PHY, and then, if Gigabit features are supported, setting those and
updating MII_CTRL1000 accordingly.
