Stephen Agate dc855b3b74 net: phy: vitesse: add support for VSC8572
Add support for the Vitesse VSC8572 which is functionally equivalent to
the already supported VSC8574. As such, all the same handling functions
are used since the VSC8572 merely has half the number of phy blocks
internally.

Alex 955e16026d net/phy/vitesse: Configure RGMII skew on VSC8601, if needed
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.

Rather than have each driver set the driver owner field, do it once in
the core code. This will also help with later changes, when the device

Kevin Hao aab0c0e62e Revert "net/phy: Add Vitesse 8641 phy ID"
This reverts commit 1298267b54.

That commit claim that the Vitesse VSC8641 is compatible with Vitesse
82xx. But this is not true. It seems that all the registers used
in Vitesse phy driver are not compatible between 8641 and 82xx.
It does cause malfunction of the Ethernet on p1010rdb-pa board.
So we definitely need a rework in order to support the 8641 phy
in this driver.

Andy Fleming fddf86fc46 phylib: Modify Vitesse RGMII skew settings
The Vitesse driver was using the RGMII_ID interface type to determine if
skew was necessary.  However, we want to move away from using that
interface type, as it's really a property of the board's PHY connection.
However, some boards depend on it, so we want to support it, while
allowing new boards to use the more flexible "fixups" approach.  To do
this, we extract the code which adds skew into its own function, and
call that function when RGMII_ID has been selected.

Another side-effect of this change is that if your PHY has skew set
already, it doesn't clear it.  This way, the fixup code can modify the
register without config_init then clearing it.

Trent Piepho 11c6dd2c72 phylib: Add Vitesse VSC8221 SGMII PHY
PHY is mostly compatible with the existing VSC8244 PHY.  The init sequence
is different and the interrupt mask lacks some bits present in the VSC8244.

Rather than making a copy of the existing VSC234x config_intr function and
change one constant, I modify it to select the interrupt mask based on
which driver is calling it.  This lets it be used by both drivers.

Andy Fleming 1d5e83aac5 Fix Vitesse 824x PHY interrupt acking
The Vitesse 824x PHY doesn't allow an interrupt to be cleared if
the mask bit for that interrupt isn't set.  This means that the PHY
Lib's order of handling interrupts (disable, then clear) breaks on this
PHY.  However, clearing then disabling the interrupt opens up the code
for a silly race condition.  So rather than change the PHY Lib, we change
the Vitesse driver so it always clears interrupts before disabling them.
Further, the ack function only clears the interrupt if interrupts are
enabled.
