This reverts commit 1298267b548a78840bd4b3e030993ff8747ca5e6.
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.

I've noticed that fixed_phy_register() ignores its 'irq' parameter instead of
passing it to fixed_phy_add(). Luckily, fixed_phy_register() seems to always
be called with PHY_POLL for 'irq'... :-)

The problem is that mdiobus_unregister() deletes the bus device before
unregistering the phy devices on the bus. This wasn't a problem before
because the phys were not children of the bus:
/sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0:03
/sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0
But now that they are:
/sys/devices/platform/APMC0D05:00/net/eth0/xgene-mii-eth0/xgene-mii-eth0:03
when mdiobus_unregister deletes the bus device, the phy subdirs are
removed from sysfs also. So when the phys are unregistered afterward,
we get the warning. This patch changes the order so that phys are
unregistered before the bus device is deleted.

What features a phy supports is masked in genphy_config_init() by
looking at the PHYs BMSR register.
If the link is down, fixed_phy_update_regs() will only set the auto-
negotiation capable bit in BMSR. Thus genphy_config_init() comes to
the conclusion the PHY can only perform 10/Half, and masks out the
higher speed features. If however the link it up, BMSR is set to
indicate the speed the PHY is capable of auto-negotiating, and
genphy_config_init() does not mask out the high speed features.
To fix this, when the link is down, have fixed_phy_update_regs() leave
the link status, auto-negotiation complete, and link partner
capabilities unset, but set all the local capabilities depending on
the fixed phy speed.

Some Ethernet MAC drivers using the PHY library require the hardcoding
of link parameters when interfaced to a switch device, SFP module,
switch to switch port, etc. This has typically lead to various ad-hoc
implementations looking like this:
- using a "fixed PHY" emulated device, which will provide link
indication towards the Ethernet MAC driver and hardware
- pretend there is no PHY and hardcode link parameters, ala mv643x_eth
Based on that, it is desireable to have the PHY drivers advertise the
correct link parameters, just like regular Ethernet PHYs towards their
CPU Ethernet MAC drivers, however, Ethernet MAC drivers should be able
to tell whether this link should be monitored or not. In the context
of an Ethernet switch, SFP module, switch to switch link, we do not
need to monitor this link since it should be always up.

The phy layer is missing locking for the above two functions - it
has been observed that two threads (userspace and the phy worker
thread) can race, entering the bus ->write or ->read functions
simultaneously.
This causes the FEC driver to initialise a completion while another
thread is waiting on it or while the interrupt is calling complete()
on it, which causes spinlock unlock-without-lock, spinlock lockups,
and completion timeouts.

commit 18ee49ddb0d2 ("phylib: rename mii_bus::dev to mii_bus::parent")
changed the parent of PHY devices from the bus to the bus parent.
Then, commit 4dea547fef1b ("phylib: rework to prepare for OF
registration of PHYs") moved the code into phy_device.c
At this point, it is somewhat unclear why the change was seen as
necessary. But, when we look at the device model tree in
/sys/devices, it is clearly incorrect. The PHYs should be children of
their MDIO bus.
Change the PHY's parent device to be the MDIO bus device.

fixed_phy_register() currently hardcodes the fixed PHY link to 1, and
expects to find a "speed" parameter to provide correct information
towards the fixed PHY consumer.
In a subsequent change, where we allow "managed" (e.g: (RS)GMII in-band
status auto-negotiation) fixed PHYs, none of these parameters can be
provided since they will be auto-negotiated, hence, we just provide a
zero-initialized fixed_phy_status to fixed_phy_register() which makes it
fail when we call fixed_phy_update_regs() since status.speed = 0 which
makes us hit the "default" label and error out.
Without this change, we would also see potentially inconsistent
speed/duplex parameters for fixed PHYs when the link is DOWN.

All BCM7xxx integrated Gigabit PHYs have an issue in their MDIO
management controller which will make the initial read or write to them
to fail and return 0xffff. This is a real issue as the typical first
thing we do is read from MII_PHYSID1 and MII_PHYSID2 from get_phy_id()
to register a driver for these PHYs.
Coupled with the workaround in drivers/net/phy/bcm7xxx.c, this
workaround for the MDIO bus controller consists in scanning the list of
PHYs to do this initial read workaround for as part of the MDIO bus
reset routine which is invoked prior to mdiobus_scan().
Once we have a proper PHY driver/device registered, all workarounds are
located there (e.g: power management suspend/resume calls).

device using acpi_dev_gpio_irq_get()
* merge some dependent I2C changes exploiting this.
* support the ARM X-Gene GPIO standby driver.
- make it possible for the generic GPIO driver to read back the value
set registers to reflect current status.
- loads of OMAP IRQ handling fixes.
- incremental improvements to Kona, max732x, OMAP, MXC, RCAR,
PCA953x, STP-XWAY, PCF857x, Crystalcove, TB10x.
- janitorial (constification, checkpatch cleanups)"
* tag 'gpio-v4.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (71 commits)

RTL8211F has different register definitions from RTL8211E.
Specially it needs to enable TXDLY in case of RGMII.

Some Ethernet PHYs/switches such as Broadcom's BCM53125 have a hardware bug
which makes them not release the MDIO line during turn-around time. This gets
flagged by the UniMAC MDIO controller as a read failure, and we fail the read
transaction.
Check the MDIO bus phy_ignore_ta_mask bitmask for the PHY we are reading
from and if it is listed in this bitmask, ignore the read failure and
proceed with returning the data we read out of the controller.

Add PHY IDs for Davicom DM9161B and DM9161C variants.
Tested with a DM9161C on a custom Atmel-based SAM9X25 board in RMII
mode.
The DM9161B uses the same model id with just the LSB bit of the version
id changing (which is masked out).
For all intents and purposes they're the same as the DM9161A with an
added GPSI mode and better fabrication process.

Fix the device tree entries to modify the '_' to '-'.
Also changes the names of the internal delay properties
from -int- to -internal- as the -int- appeared as a keyword.
