When the T1 phy master/slave state is changed, at the end of config_aneg
function genphy_softreset is called. After the reset all the registers
configured during the config_init are restored to default value.
To avoid this, removed the genphy_softreset call.

Add cable test support for Micrel KSZ9x31 PHYs.
Tested on i.MX8M Mini with KSZ9131RNX in 100/Full mode with pairs shuffled
before magnetics:
(note: Cable test started/completed messages are omitted)
mx8mm-ksz9131-a-d-connected$ ethtool --cable-test eth0
Pair A code OK
Pair B code Short within Pair
Pair B, fault length: 0.80m
Pair C code Short within Pair
Pair C, fault length: 0.80m
Pair D code OK
mx8mm-ksz9131-a-b-connected$ ethtool --cable-test eth0
Pair A code OK
Pair B code OK
Pair C code Short within Pair
Pair C, fault length: 0.00m
Pair D code Short within Pair
Pair D, fault length: 0.00m
Tested on R8A77951 Salvator-XS with KSZ9031RNX and all four pairs connected:
(note: Cable test started/completed messages are omitted)
r8a7795-ksz9031-all-connected$ ethtool --cable-test eth0
Pair A code OK
Pair B code OK
Pair C code OK
Pair D code OK
The CTRL1000 CTL1000_ENABLE_MASTER and CTL1000_AS_MASTER bits are not
restored by calling phy_init_hw(), they must be manually cached in
ksz9x31_cable_test_start() and restored at the end of

When the PHY and the MAC are capable of doing timestamping, the PHY has
priority. Therefore the DT option lan8814,ignore-ts was added such that
the PHY will not expose a PHC so then the timestamping was done in the
MAC. This is not the correct approach of doing it, therefore remove
this.

A Broadcom AC201 PHY (same entry as 5241) would be flagged by the
Broadcom UniMAC MDIO controller as not completing the turn around
properly since the PHY expects 65 MDC clock cycles to complete a write
cycle, and the MDIO controller was only sending 64 MDC clock cycles as
determined by looking at a scope shot.
This would make the subsequent read fail with the UniMAC MDIO controller
command field having MDIO_READ_FAIL set and we would abort the
brcm_fet_config_init() function and thus not probe the PHY at all.
After issuing a software reset, wait for at least 1ms which is well
above the 1us reset delay advertised by the datasheet and issue a dummy
read to let the PHY turn around the line properly. This read
specifically ignores -EIO which would be returned by MDIO controllers
checking for the line being turned around.
If we have a genuine reaad failure, the next read of the interrupt
status register would pick it up anyway.

lan8814_match_rx_ts() invokes netif_rx() with disables interrupts
outside which will create a warning. Invoking netif_rx_ni() with
disabled interrupts is wrong even without the recent rework because
netif_rx_ni() would enable interrupts while processing the softirq. This
in turn can lead to dead lock if an interrupts triggers and attempts to
acquire kszphy_ptp_priv::rx_ts_lock.

This PHY doesn't support a link-up interrupt source. If aneg is enabled
we use the "aneg complete" interrupt for this purpose, but if aneg is
disabled link-up isn't signaled currently.
According to a vendor driver there's an additional "energy detect"
interrupt source that can be used to signal link-up if aneg is disabled.
We can safely ignore this interrupt source if aneg is enabled.
This patch was tested on a TX3 Mini TV box with S905W (even though
boot message says it's a S905D).
This issue has been existing longer, but due to changes in phylib and
the driver the patch applies only from the commit marked as fixed.

The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

It is mandatory for a software to issue a reset upon modifying RGMII
Receive Timing Control and RGMII Transmit Timing Control bit fields of MAC
Specific Control register 2 (page 2, register 21) otherwise the changes
won't be perceived by the PHY (the same is applicable for a lot of other
registers). Not setting the RGMII delays on the platforms that imply it'
being done on the PHY side will consequently cause the traffic loss. We
discovered that the denoted soft-reset is missing in the
m88e1121_config_aneg() method for the case if the RGMII delays are
modified but the MDIx polarity isn't changed or the auto-negotiation is
left enabled, thus causing the traffic loss on our platform with Marvell
Alaska 88E1510 installed. Let's fix that by issuing the soft-reset if the
delays have been actually set in the m88e1121_config_aneg_rgmii_delays()
method.

When setting up autonegotiation for 88E1118R and compatible PHYs,
a software reset of PHY is issued before setting up polarity.
This is incorrect as changes of MDI Crossover Mode bits are
disruptive to the normal operation and must be followed by a
software reset to take effect. Let's patch m88e1118_config_aneg()
to fix the issue mentioned before by invoking software reset
of the PHY just after setting up MDI-x polarity.

phylink_set_10g_modes() is no longer used with the conversion of
drivers to phylink_generic_validate(), so we can remove it.

A typo in qca808x_read_status means we try to set SMII mode on the port
rather than SGMII when the link speed is not 2.5Gb/s. This results in no
traffic due to the mismatch in configuration between the phy and the
mac.
v2:
Only change interface mode when the link is up

After following the call tree of phy_set_max_speed(), it became clear
that this function never returns anything but 0, so we can change its
result type to *void* and drop the result checks from the three drivers
that actually bothered to do it...

Add support for downstream SFP cages for AR8031 and AR8033. This is
primarily intended for fiber modules or direct-attach cables, however
copper modules which work in 1000Base-X mode may also function. Such
modules are allowed with a warning.
