I recently posted a patch ("storage: Add quirk for another SCM-based
USB-SCSI converter") to add a quirk for the converter with ID 04E6:000F,
which is listed along with 04E6:000B in the Windows INF file for the
Startech ICUSBSCSI2 as "eUSB SCSI Adapter (Bus Powered)".
The already-present quirk for 04E6:000B has USB_SC_SCSI/USB_PR_BULK, not
USB_SC_DEVICE/USB_PR_DEVICE. Change the 04E6:000F quirk to match that,
since it will probably be required.

Intel Wired LAN Driver Updates 2015-01-22
This series contains updates to e1000, e1000e, igb, fm10k and virtio_net.
Asaf Vertz provides a fix for e1000 to future-proof the time comparisons
by using time_after_eq() instead of plain math.
Mathias Koehrer provides a fix for e1000e to add a check to e1000_xmit_frame()
to ensure a work queue will not be scheduled that has not been initialized.
Jacob adds the use of software timestamping via the virtio_net driver.
Alex Duyck cleans up page reuse code in igb and fm10k. Cleans up the
page reuse code from getting into a state where all the workarounds
needed are in place as well as cleaning up oversights, such as using
__free_pages instead of put_page to drop a locally allocated page.
Richard Cochran provides 4 patches for igb dealing with time sync.
First provides a helper function since the code that handles the time
sync interrupt is repeated in three different places. Then serializes
the access to the time sync interrupt since the registers may be
manipulated from different contexts. Enables the use of i210 device
interrupt to generate an internal PPS event for adjusting the kernel
system time. The i210 device offers a number of special PTP hardware
clock features on the Software Defined Pins (SDPs), so added support for
two of the possible functions (time stamping external events and
periodic output signals).
Or Gerlitz fixes fm10k from double setting of NETIF_F_SG since the
networking core does it for the driver during registration time.
Joe Stringer adds support for up to 104 bytes of inner+outer headers in
fm10k and adds an initial check to fail encapsulation offload if these
are too large.
Matthew increases the timeout for the data path reset based on feedback
from the hardware team, since 100us is too short of a time to wait for
the data path reset to complete.
Alexander Graf provides a fix for igb to indicate failure on VF reset
for an empty MAC address, to mirror the behavior of ixgbe.
Florian Westphal updates e1000 and e1000e to support txtd update delay
via xmit_more, this way we won't update the Tx tail descriptor if the
queue has not been stopped and we know at least one more skb will be
sent right away.

In the vxlan transmit path there is no need to reference the socket
for a tunnel which is needed for the receive side. We do, however,
need the vxlan_dev flags. This patch eliminate references
to the socket in the transmit path, and changes VXLAN_F_UNSHAREABLE
to be VXLAN_F_RCV_FLAGS. This mask is used to store the flags
applicable to receive (GBP, CSUM6_RX, and REMCSUM_RX) in the
vxlan_sock flags.

The UDP tunnel transmit functions udp_tunnel_xmit_skb and
udp_tunnel6_xmit_skb include a socket argument. The socket being
passed to the functions (from VXLAN) is a UDP created for receive
side. The only thing that the socket is used for in the transmit
functions is to get the setting for checksum (enabled or zero).
This patch removes the argument and and adds a nocheck argument
for checksum setting. This eliminates the unnecessary dependency
on a UDP socket for UDP tunnel transmit.

There have one bug in .fec_enet_tx_queue() function to unmap the DMA memory:
For SG or TSO, get one buffer descriptor and then unmap the related DMA memory, and then
get the next buffer descriptor, loop to while() to check "TX_READY". If "TX_READY" bit
still __IS__ existed in the BD (The next fraglist or next TSO packet is not transmited
complitely), exit the current clean work. When the next work is triggered, it still repeat
above step with the same BD. The potential issue is that unmap the same DMA memory for
multiple times.
The patch fix the clean work for SG and TSO packet.

be2net: patch set
Hi David, as the below patch-set includes minor bug fixes and some
code re-org, pls consider applying it to the "net-next" tree. Thanks!
Patch 1 fixes a bit of code duplication involving interface object
creation code.
Patch 2 ensures that when a flow-control FW cmd fails, the adapter state
continues to reflect the old values. This allows for correct reporting
on subsequent ethtool "get".
Patch 3 returns proper error for link config change on BE3/Lancer
Patch 4 adds a kernel log message for FW boot error on Lancer
Patch 5 adds a function reset on Lancer as a part of the function init
sequence.
Patch 6 moves some FW-cmd definitions that belong in be_cmds.h, but
were placed in be_hw.h
Patch 7 resets the "bw_min" field while configuring "bw_max" needed
for TX rate limiting config.

net: stmmac: dwmac-rk: Fix phy regulator issues
This series fixes few issues in dwmac-rk:
1. Voltage settings was hardcoded into the driver for the phy regulator.
The driver now uses the default voltage settings found in the devicetree,
which are applied throught the regulator framework.
2. The regulator name used to power on or power off the phy was put in the devicetree
variable "phy_regulator", which is not standard and added a lot of code for nothing.
The driver now uses the devicetree property "phy-supply" and the corresponding functions
to manipulate this regulator.
The corresponding devicetree files are also updated. As this new binding for
rk3288 has not been released with any official kernel yet (not until 3.20),
I don't need to care about keeping compatibility with the old non standard property.

Currently, dwmac-rk uses a custom propety "phy_regulator" to get the name of the
right regulator to use to power on or power off the phy. This commit converts the
driver to use phy-supply devicetree property and the corresponding API, it cleans
the code a bit and make it simpler to maintain. This also replaces the property
phy_regulator by the standard property phy-supply in rk3288-evb-rk808.dts.

As these settings can be directly expressed from devicetree for both fixed
regulators and pmic-integrated regulators, it is more standard to set them
from dts and let the regulator framework use the right voltage informations
when it is used in the driver.

Pull hwmon update from Jean Delvare:
"This contains a single thing: a new driver for the temperature sensor
embedded in the Intel 5500/5520/X58 chipsets.
Sorry for the late request, it's been so long since I last sent a pull
request and I've been so busy with other tasks meanwhile that I simply
forgot about these patches. But given that this is a new driver, it
can't introduce any regression so I thought it could still be OK.
This has been in linux-next for months now"

Commit ffcc393641 ("dm: enhance internal suspend and resume interface")
attempted to handle multiple internal suspends on the same device, but
it did that incorrectly. When these functions are called in this order
on the same device the device is no longer suspended, but it should be:
dm_internal_suspend_noflush
dm_internal_suspend_noflush
dm_internal_resume
Fix this bug by maintaining an 'internal_suspend_count' and resuming
the device when this count drops to zero.

On many motherboards, for an unknown reason, the thermal sensor seems
to be disabled and will return a constant temperature value of 36.5
degrees Celsius. Don't bind to the device in that case, so that we
don't report this bogus value to userspace.

The Intel 5500, 5520 and X58 chipsets embed a digital thermal sensor.
This new driver supports it.
Note that on many boards the sensor seems to be disabled and reports
the minimum value (36.5 degrees Celsius) all the time.

Updated hardware documention shows the Rx flow control settings were
moved from the Rx queue operation mode register to a new Rx queue flow
control register. The old flow control settings are now reserved areas
of the Rx queue operation mode register. Update the code to use the new
register.

This patch solves deadlock between clock prepare mutex and regmap mutex reported
by Tomasz Figa in [1] by implementing solution from [2]: "always leave the clock
of the i2c controller in a prepared state".
[1] https://lkml.org/lkml/2014/7/2/171
[2] https://lkml.org/lkml/2014/7/2/207
On each i2c transfer handled by s3c24xx_i2c_xfer(), clk_prepare_enable() was
called, which calls clk_prepare() then clk_enable(). clk_prepare() takes
prepare_lock mutex before proceeding. Note that i2c transfer functions are
invoked from many places in kernel, typically with some other additional lock
held.
It may happen that function on CPU1 (e.g. regmap_update_bits()) has taken a
mutex (i.e. regmap lock mutex) then it attempts i2c communication in order to
proceed (so it needs to obtain clock related prepare_lock mutex during transfer
preparation stage due to clk_prepare() call). At the same time other task on
CPU0 wants to operate on clock (e.g. to (un)prepare clock for some other reason)
so it has taken prepare_lock mutex.
CPU0: CPU1:
clk_disable_unused() regulator_disable()
clk_prepare_lock() map->lock(map->lock_arg)
regmap_read() s3c24xx_i2c_xfer()
map->lock(map->lock_arg) clk_prepare_lock()
Implemented solution from [2] leaves i2c clock prepared. Preparation is done in
s3c24xx_i2c_probe() function. Without this patch, it is immediately unprepared
by clk_disable_unprepare() call. I've replaced this call with clk_disable() and
I've added clk_unprepare() call in s3c24xx_i2c_remove().
The s3c24xx_i2c_xfer() function now uses clk_enable() instead of
clk_prepare_enable() (and clk_disable() instead of clk_unprepare_disable()).
