Srinivas Kandagatla b3300146aa phy:icplus:fix Auto Power Saving in ip101a_config_init.
This patch fixes Auto Power Saving configuration in ip101a_config_init
which was broken as there is no phy register write followed after
setting IP101A_APS_ON flag.

This patch also fixes the return value of ip101a_config_init.

Without this patch ip101a_config_init returns 2 which is not an error
accroding to IS_ERR and the mac driver will continue accessing 2 as
valid pointer to phy_dev resulting in memory fault.

Linus Torvalds c207f3a431 Generialize powerpc's irq_host as irq_domain
This branch takes the PowerPC irq_host infrastructure (reverse mapping
 from Linux IRQ numbers to hardware irq numbering), generalizes it,
 renames it to irq_domain, and makes it available to all architectures.
 
 Originally the plan has been to create an all-new irq_domain
 implementation which addresses some of the powerpc shortcomings such
 as not handling 1:1 mappings well, but doing that proved to be far
 more difficult and invasive than generalizing the working code and
 refactoring it in-place.  So, this branch rips out the 'new'
 irq_domain and replaces it with the modified powerpc version (in a
 fully bisectable way of course).  It converts all users over to the
 new API and makes irq_domain selectable on any architecture.
 
 No architecture is forced to enable irq_domain, but the infrastructure
 is required for doing OpenFirmware style irq translations.  It will
 even work on SPARC even though SPARC has it's own mechanism for
 translating irqs at boot time.  MIPS, microblaze, embedded x86 and c6x
 are converted too.
 
 The resulting irq_domain code is probably still too verbose and can be
 optimized more, but that can be done incrementally and is a task for
 follow-on patches.

Also the patch does a simple dity-up to signal that
the driver actually is for IP101A LF and IP101G devices.
In fact, these are two similar PHYs that have the same IDs
and mainly differ for the EEE capability supported in the
G series.

David McKay b8e3995af4 netdev/phy/icplus: Correct broken phy_init code
The code for ip1001_config_init() was totally broken if you were not
using RGMII. Instead of returning an error code or zero it actually
returned the value in the IP1001_SPEC_CTRL_STATUS_2 register. It was
also trying to set the IP1001_APS_ON bit , but never actually wrote
back the register.

The error checking was also incorrect in both this function and the
reset function, so this patch fixes that up in a consistent fashion.

Timur Tabi eb8a54a78e phylib: introduce mdiobus_alloc_size()
Introduce function mdiobus_alloc_size() as an alternative to mdiobus_alloc().
Most callers of mdiobus_alloc() also allocate a private data structure, and
then manually point bus->priv to this object.  mdiobus_alloc_size()
combines the two operations into one, which simplifies memory management.

The original mdiobus_alloc() now just calls mdiobus_alloc_size(0).

Dirk Eibach f42af6c486 net: Fix driver name for mdio-gpio.c
Since commit
"7488876... dt/net: Eliminate users of of_platform_{,un}register_driver"
there are two platform drivers named "mdio-gpio" registered.
I renamed the of variant to "mdio-ofgpio".

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.

Giuseppe CAVALLARO a4886d522e net/phy: extra delay only for RGMII interfaces for IC+ IP 1001
The extra delay of 2ns to adjust RX clock phase is actually needed
in RGMII mode. Tested on the HDK7108 (STx7108c2).

David Daney 76231e0297 netdev/phy/icplus: Use mdiobus_write() and mdiobus_read() for proper locking.
Usually you have to take the bus lock.  Why not here too?

I saw this when working on something else.  Not even compile tested.

David Daney 6fe3264945 netdev/phy: Use mdiobus_read() so that proper locks are taken.
Accesses to the mdio busses must be done with the mdio_lock to ensure
proper operation.  Conveniently we have the helper function
mdiobus_read() to do that for us.  Lets use it in get_phy_id() instead
of accessing the bus without the lock held.

Richard Cochran 02715ed2e7 dp83640: reduce driver noise
The driver has two warning messages that might be triggered
by normal use cases. When they appear, the messages give the
impression of a never ending series of errors.

This commit changes them to debug messages instead.

Richard Cochran 49b3fd4aff dp83640: enable six external events and one periodic output
This patch enables six external event channels and one periodic output.
One GPIO is reserved for synchronizing multiple PHYs. The assignment
of GPIO functions can be changed via a module parameter.

The code supports multiple simultaneous events by inducing a PTP clock
event for every channel marked in the PHY's extended status word.

Jeff Kirsher 88491d8103 drivers/net: Kconfig & Makefile cleanup
The is does a general cleanup of the drivers/net/ Kconfig and
Makefile.  This patch create a "core" option and places all
the networking core drivers into this option (default is yes
for this option).  In addition, it alphabitizes the Kconfig
driver options.

As a side cleanup, found that the arcnet, token ring, and PHY
Kconfig options were a tri-state option and should have been
a bool option.

Richard Cochran 8028837d71 dp83640: increase receive time stamp buffer size
The dp83640 buffers receive time stamps from special PHY status frames,
matching them to received PTP packets in a work queue. Because the timeout
for orphaned time stamps is so long and the buffer is so small, the driver
can drop time stamps under moderate PTP traffic.

This commit fixes the issue by decreasing the timeout to (at least) one
timer tick and increasing the buffer size.
