<title>net/phy/vitesse: Configure RGMII skew on VSC8601, if needed</title>

<content type='text'>
With RGMII, we need a 1.5 to 2ns skew between clock and data lines. The
VSC8601 can handle this internally. While the VSC8601 can set more
fine-grained delays, the standard skew settings work out of the box.
The same heuristic is used to determine when this skew should be enabled
as in vsc824x_config_init().

Tested on custom board with AM3352 SOC and VSC801 PHY.

Make sure to drop the reference taken by bus_find_device_by_name()
before returning from phy_connect() and phy_attach().

Note that both function still take a reference to the phy device
through phy_attach_direct().

<title>at803x: double check SGMII side autoneg</title>

<id>f62265b53ef34a372b657c99e23d32e95b464316</id>
<content type='text'>
In SGMII mode, we observed an autonegotiation issue
after power-down-up cycles where the copper side
reports successful link establishment but the
SGMII side's link is down.

This happened in a setup where the at8031 is
connected over SGMII to a eTSEC (fsl gianfar),
but so far could not be reproduced with other
Ethernet device / driver combinations.

This commit adds a wrapper function for at8031
that in case of operating in SGMII mode double
checks SGMII link state when generic aneg_done()
succeeds. It prints a warning on failure but
intentionally does not try to recover from this
state. As a result, if you ever see a warning
'803x_aneg_done: SGMII link is not ok' you will
end up having an Ethernet link up but won't get
any data through. This should not happen, if it
does, please contact the module maintainer.

This reverts commit 98267311fe3b334ae7c107fa0e2413adcf3ba735.

Suspending the SGMII alongside the copper side
made the at803x inaccessable while powered down,
e.g. it can't be re-probed after suspend.

<title>net: phy: Trigger state machine on state change and not polling.</title>

<content type='text'>
The phy_start() is used to indicate the PHY is now ready to do its
work. The state is changed, normally to PHY_UP which means that both
the MAC and the PHY are ready.

If the phy driver is using polling, when the next poll happens, the
state machine notices the PHY is now in PHY_UP, and kicks off
auto-negotiation, if needed.

If however, the PHY is using interrupts, there is no polling. The phy
is stuck in PHY_UP until the next interrupt comes along. And there is
no reason for the PHY to interrupt.

Have phy_start() schedule the state machine to run, which both speeds
up the polling use case, and makes the interrupt use case actually
work.

This problems exists whenever there is a state change which will not
cause an interrupt. Trigger the state machine in these cases,
e.g. phy_error().
