The PTP reference clock, used for setting the addend in the Timestamp Addend
Register, was erroneously hard-coded (as reported in the databook just as
example).
The patch removes the macro named: STMMAC_SYSCLOCK and allows to use a
reference clock (clk_ptp_ref_i) that can be passed from the platform.
If not passed, the main driver clock will be used as default; note that
this can be fine on some platforms.
Note that, prior this patch, using the old STMMAC_SYSCLOCK on some platforms,
as side effect, the ptp clock can move faster/slower than the system clock.

For the NFC bits, Samuel says:
"This is a rather quiet one, we have:
- A new driver from ST Microelectronics for their NCI ST21NFCB,
including device tree support.
- p2p support for the ST21NFCA driver
- A few fixes an enhancements for the NFC digital laye"
For the Atheros bits, Kalle says:
"Michal and Janusz did some important RX aggregation fixes, basically we
were missing RX reordering altogether. The 10.1 firmware doesn't support
Ad-Hoc mode and Michal fixed ath10k so that it doesn't advertise Ad-Hoc
support with that firmware. Also he implemented a workaround for a KVM
issue."
For the Bluetooth bits, Gustavo and Johan say:
"To quote Gustavo from his previous request:
'Some last minute fixes for -next. We have a fix for a use after free in
RFCOMM, another fix to an issue with ADV_DIRECT_IND and one for ADV_IND with
auto-connection handling. Last, we added support for reading the codec and
MWS setting for controllers that support these features.'
Additionally there are fixes to LE scanning, an update to conform to the 4.1
core specification as well as fixes for tracking the page scan state. All
of these fixes are important for 3.17."
And,
"We've got:
- 6lowpan fixes/cleanups
- A couple crash fixes, one for the Marvell HCI driver and another in LE SMP.
- Fix for an incorrect connected state check
- Fix for the bondable requirement during pairing (an issue which had
crept in because of using "pairable" when in fact the actual meaning
was "bondable" (these have different meanings in Bluetooth)"

brcmfmac and b43 as well as a stray ath9k patch.

therefore parameters are required. The Altera Cyclone V SOC has support for

Describe the properties used by the st21nfca NFC controller driver.
Signed-off-by: Christophe Ricard <christophe-h.ricard@st.com>
Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
Some Ethernet MACs have a "fixed link", and are not connected to a
normal MDIO-managed PHY device. For those situations, a Device Tree
binding allows to describe a "fixed link" using a special PHY node.
This patch adds:
* A documentation for the fixed PHY Device Tree binding.
* An of_phy_is_fixed_link() function that an Ethernet driver can call
on its PHY phandle to find out whether it's a fixed link PHY or
not. It should typically be used to know if
of_phy_register_fixed_link() should be called.
* An of_phy_register_fixed_link() function that instantiates the
fixed PHY into the PHY subsystem, so that when the driver calls
of_phy_connect(), the PHY device associated to the OF node will be
found.
These two additional functions also support the old fixed-link Device
Tree binding used on PowerPC platforms, so that ultimately, the
network device drivers for those platforms could be converted to use
of_phy_is_fixed_link() and of_phy_register_fixed_link() instead of
of_phy_connect_fixed_link(), while keeping compatibility with their
respective Device Tree bindings.

This commit adds the necessary definitions for the PHY layer to
recognize "qsgmii" as a valid PHY interface. A QSMII interface, as
defined at
http://en.wikipedia.org/wiki/Media_Independent_Interface#Quad_Serial_Gigabit_Media_Independent_Interface,
is "is a method of combining four SGMII lines into a 5Gbit/s
interface. QSGMII, like SGMII, uses LVDS signalling for the TX and RX
data and a single LVDS clock signal. QSGMII uses significantly fewer
signal lines than four SGMII busses."
This type of MAC <-> PHY connection might require special handling on
the MAC driver side, so it should be possible to express this type of
MAC <-> PHY connection, for example in the Device Tree.

A large part of the arm-soc patches are nowadays DT changes, adding support
for new SoCs, boards and devices without changing kernel source. The plan
is still to move the devicetree files out of the kernel tree and reduce
the amount of churn going on here, but we keep finding reasons to delay
doing that.
Changes are really all over the place, with little sticking out particularly.
We have contributions from a total of 116 people in this branch.
Unfortunately, the size of this branch also causes a significant number
of conflicts at the moment, typically when subsystem maintainers merge
patches that change the driver at the same time as the dts files. In
most cases this could be avoided because the dts changes are supposed
to be compatible in both ways, and we are asking everyone to send ARM
dts changes through our tree only.

device_type is deprecated and the kernel doesn't require it in most
cases. The only exceptions for flat tree users are the "gianfar",
"ucc_geth" and "ibm,emac" bindings, and arguably that requirement could
be relaxed for ucc_geth and ibm,emac (that is a task for separate
patches though).
This patch removes references to device_type="network" from the binding
documentation where possible and removes the properties from ARM and
microblaze dts files. This patch does not modify the powerpc .dts files
since there are a much larger number of them affected and I think the
ucc_geth, ibm,emac and gianfar users should be addressed before clearing
out the references to reduce the chance of breakage.

The linux,phandle property is essentially an internal structural element
of the DT data structure. The dtc toolchain takes care of maintaining it
at compile time. It does not need to appear as part of the binding
documentation. This patch removes it so that users don't think they need
to add a phandle property manually.

The device_type property is deprecated for the flattened device tree and
the value "ethernet-phy" has never been defined as having a useful
meaning. Neither the kernel nor u-boot depend on it. It should never
have appeared in PHY bindings. This patch removes all references to
"ethernet-phy" as a device_type value from the documentation and the
.dts files.
This patch was generated mechanically with the following command and
then verified by looking at the diff.

Fix the issue by parsing the necessary configuration like the

When booted with device tree, we may still have platform data passed
as auxdata. For am3517 this is needed for passing the interrupt_enable
and interrupt_disable callbacks that access the omap system control module
registers. These callback functions will eventually go away when we have
a separate system control module driver.
Some of the things that are currently passed as platform data we don't need
to set up as device tree properties as they are always the same on am3517.
So let's use a new compatible flag for those so we can get those from
the device tree match data.
Also note that we need to fix setting of phy_dev to NULL instead of an empty
string as the code later on uses that to find the first phy on the mdio bus.
This seems to have been caused by 5d69e0076a (net: davinci_emac: switch to

The cpsw currently lacks code to properly set up the hardware interface
mode on AM33xx. Other platforms might be equally affected.
Usually, the bootloader will configure the control module register, so
probably that's why such support wasn't needed in the past. In suspend
mode though, this register is modified, and so it needs reprogramming
after resume.
This patch adds a new driver in which hardware interface can configure
correct register bits when the slave is opened.
The AM33xx also has a bit for each slave to configure the RMII reference
clock direction. Setting it is now supported by a per-slave DT property.
This code path introducted by this patch is currently exclusive for
am33xx and same can be extened to various platforms via the DT compatibility
property.

This is a rather large set of patches for device drivers that for one
reason or another the subsystem maintainer preferred to get merged
through the arm-soc tree. There are both new drivers as well as
existing drivers that are getting converted from platform-specific
code into standalone drivers using the appropriate subsystem
specific interfaces.
In particular, we can now have pinctrl, clk, clksource and irqchip
drivers in one file per driver, without the need to call into
platform specific interface, or to get called from platform specific
code, as long as all information about the hardware is provided
through a device tree.
Most of the drivers we touch this time are for clocksource. Since
now most of them are part of drivers/clocksource, I expect that we
won't have to touch these again from arm-soc and can let the
clocksource maintainers take care of these in the future.
Another larger part of this series is specific to the exynos platform,
which is seeing some significant effort in upstreaming and
modernization of its device drivers this time around, which
unfortunately is also the cause for the churn and a lot of the
merge conflicts.
There is one new subsystem that gets merged as part of this series:
the reset controller interface, which is a very simple interface
for taking devices on the SoC out of reset or back into reset.
Patches to use this interface on i.MX follow later in this merge
window, and we are going to have other platforms (at least tegra
and sirf) get converted in 3.11. This will let us get rid of
platform specific callbacks in a number of platform independent
device drivers.

Now that the Armada 370/XP platform has gained proper integration with
the clock framework, we add clk support in the Marvell Armada 370/XP
Ethernet driver.
Since the existing Device Tree binding that exposes a
'clock-frequency' property has never been exposed in any stable kernel
release, we take the freedom of removing this property to replace it
with the standard 'clocks' clock pointer property.
The Device Tree binding documentation is updated accordingly.

When the mdio-gpio driver is probed via device trees, the platform
device id is set as -1, However the pdev->id is re-used as bus-id for
while creating mdio gpio bus.
So
For device tree case the mdio-gpio bus name appears as "gpio-ffffffff"
where as
for non-device tree case the bus name appears as "gpio-<bus-num>"
Which means the bus_id is fixed in device tree case, so we can't have
two mdio gpio buses via device trees. Assigning a logical bus number
via device tree solves the problem and the bus name is much consistent
with non-device tree bus name.
Without this patch
1. we can't support two mdio-gpio buses via device trees.
2. we should always pass gpio-ffffffff as bus name to phy_connect, very
different to non-device tree bus name.
So, setting up the bus_id via aliases from device tree is the right
solution and other drivers do similar thing.

This patch contains a new network driver for the network unit of the
ARM Marvell Armada 370 and the Armada XP. Both SoCs use the PJ4B
processor, a Marvell-developed ARM core that implements the ARMv7
instruction set.
Compared to previous ARM Marvell SoCs (Kirkwood, Orion, Discovery),
the network unit in Armada 370 and Armada XP is highly different. This
is the reason why this new 'mvneta' driver is needed, while the older
ARM Marvell SoCs use the 'mv643xx_eth' driver.
Here is an overview of the most important hardware changes that
require a new, specific, driver for the network unit of Armada 370/XP:
- The new network unit has a completely different design and layout
for the RX and TX descriptors. They are now organized as a simple
array (each RX and TX queue has base address and size of this
array) rather than a linked list as in the old SoCs.
- The new network unit has a different RXQ and TXQ management: this
management is done using special read/write counter registers,
while in the Old SocS, it was done using the Ownership bit in RX
and TX descriptors.
- The new network unit has different interrupt registers
- The new network unit way of cleaning of interrupts is not done by
writing to the cause register, but by updating per-queue counters
- The new network unit has different GMAC registers (link, speed,
duplex configuration) and different WRR registers.
- The new network unit has lots of new units like PnC (Parser and
Classifier), PMT, BM (Memory Buffer Management), xPON, and more.
The driver proposed in the current patch only handles the basic
features. Additional hardware features will progressively be supported
as needed.
This code has originally been written by Rami Rosen
<rosenr@marvell.com>, and then reviewed and cleaned up by Thomas
Petazzoni <thomas.petazzoni@free-electrons.com>.

This patch adds a separate driver for the MDIO interface of the
Marvell Ethernet controllers. There are two reasons to have a separate
driver rather than including it inside the MAC driver itself:
*) The MDIO interface is shared by all Ethernet ports, so a driver
must guarantee non-concurrent accesses to this MDIO interface. The
most logical way is to have a separate driver that handles this
single MDIO interface, used by all Ethernet ports.
*) The MDIO interface is the same between the existing mv643xx_eth
driver and the new mvneta driver. Even though it is for now only
used by the mvneta driver, it will in the future be used by the
mv643xx_eth driver as well.

The two device tree files octeon_3xxx.dts and octeon_68xx.dts are
trimmed by code in a subsequent patch to reflect the hardware actually
present on the board. To this end several properties that are not
part of the declared bindings are added to aid in trimming off
unwanted nodes. Since the device tree and the code that trims it are
bound into the kernel binary, these 'marker' properties never escape
into the wild, and are purely an implementation detail of the kernel
early boot process. This is done for backwards compatibility with
existing boards (identified by a board type enumeration value by their
bootloaders). New boards will always pass a device tree from the
bootloader, the built-in trees are ignored in this case.

If a PHY is "compatible" with "ethernet-phy-ieee802.3-c45", we

If get_phy_device() fails, it was probably due to failing the probe of
the PHY identifier registers. Since we have the device tree telling
us the PHY exists, go ahead and add it anyhow with a phy_id of zero.

This patch adds a somewhat generic framework for MDIO bus
multiplexers. It is modeled on the I2C multiplexer.
The multiplexer is needed if there are multiple PHYs with the same
address connected to the same MDIO bus adepter, or if there is
insufficient electrical drive capability for all the connected PHY
devices.
Conceptually it could look something like this:
------------------
| Control Signal |
--------+---------
|
--------------- --------+------
| MDIO MASTER |---| Multiplexer |
--------------- --+-------+----
| |
C C
h h
i i
l l
d d
| |
--------- A B ---------
| | | | | |
| PHY@1 +-------+ +---+ PHY@1 |
| | | | | |
--------- | | ---------
--------- | | ---------
| | | | | |
| PHY@2 +-------+ +---+ PHY@2 |
| | | |
--------- ---------
This framework configures the bus topology from device tree data. The
mechanics of switching the multiplexer is left to device specific
drivers.
The follow-on patch contains a multiplexer driven by GPIO lines.

parsing the device tree. Clocks and initial io mappings are still
configured statically.
This patch still depends on some static platform_data for a few devices
which is passed via the auxdata structure to of_platform_populate(),
but it is a viable starting point until the drivers can get all
