This patch adds kernel support for the meta expression in get/set
flavour. The set operation indicates that a given packet has to be
set with a property, currently one of mark, priority, nftrace.
The get op is what was currently working: evaluate the given
packet property.
In the nftrace case, the value is always 1. Such behaviour is copied
from net/netfilter/xt_TRACE.c
The NFTA_META_DREG and NFTA_META_SREG attributes are mutually
exclusives.

When we set burst to 1514 with low rate in userspace,
the kernel get a value of burst that less than 1514,
which doesn't work.
Because it may make some loss when transform burst
to buffer in userspace. This makes burst lose some
bytes, when the kernel transform the buffer back to
burst.
This patch adds two new attributes to support sending
burst/mtu to kernel directly to avoid the loss.

ARM: tegra: implement common DMA and resets DT bindings
This series converts the Tegra DTs and drivers to use the common/
standard DMA and reset bindings, rather than custom bindings. It also
adds complete documentation for the Tegra clock bindings without
actually changing any binding definitions.
This conversion relies on a few sets of patches in branches from outside
the Tegra tree:
1) A patch to add an DMA channel request API which allows deferred probe
to be implemented.
2) A patch to implement a common part of the of_xlate function for DMA
controllers.
3) Some ASoC patches (which in turn rely on (1) above), which support
deferred probe during DMA channel allocation.
4) The Tegra clock driver changes for 3.14.
Consequently, this branch is based on a merge of all of those external
branches.
In turn, this branch is or will be pulled into a few places that either
rely on features introduced here, or would otherwise conflict with the
patches:
a) Tegra's own for-3.14/powergate and for-4.14/dt branches, to avoid
conflicts.
b) The DRM tree, which introduces new code that relies on the reset
controller framework introduced in this branch, and to avoid
conflicts.

Jonathan writes:
2nd round of new IIO drivers, features and cleanups for the 3.14 cycle.
New drivers
* HID inclinometer driver.
* DHT11 humidity driver. Note that previous humidity drivers have been in
hwmon, but no one was ever entirely happy with that, and they should find
a more comfortable home in IIO (their original placement in hwmon was my
fault - oops). As this is our first humidity driver, core support is also
added.
New features
* Two of mxs-lradc channels are internally wired to a temperature sensor,
make this explicit in the driver by providing the relevant temperature
channel.
* Add support for blocking IO on buffers.
* Add a data_available call back to the interface between buffer implementations
and the core. This is much cleaner than the old, 'stufftoread' flag.
Implemented in the kfifo buffer.
Cleanups
* Last user of the old event configuration interface is converted and the
old interface dropped. Nice to be rid of this thanks to Lars-Peter's hard
work!
* Replace all remaining instances of the IIO_ST macro with explicit filling
of the scan_type structure within struct iio_chan_spec. This macro was a
bad idea, that rapidly ceased to cover all elements of the structure.
Miss reading of the macro arguements has led to a number of bugs so lets
just get rid of it. The final removal patch is awaiting for some fixes
to make their way into mainline.
In a couple of drivers, no elements of scan_type were even being used so
in those case, it has been dropped entirely.
* Drop a couple of of_match_ptr helper uses in drivers where devicetree is
not optional and hence the structures being protected by this always exist.
* Fix up some cases where data was read from a device in a particular
byte order, but he code placed it into a s16 or similar. These were
highlighted by Sparse.
* Use the new ATTRIBUTE_GROUPS macro to drop some boiler plate in the triggers
core code.
* ad7746 and ad7280a - stop storing buffers on the stack, giving cleaner code
and possibly avoiding issues with i2c bus drivers that assume they can dma
directly into the buffer. Note that this cannot currently happen as the the
i2c_smbus_read_i2c_block_data function has a memcpy from the buffer actually
passed to the bus driver. I missed this element of the commit message
and don't think it is major enough to rebase the iio tree.
* ad5791 and ad5504 stop storing buffers on the stack for an SPI driver.
Unlike the i2c drivers, this is a real issue for SPI drivers which can dma
directly into the buffer supplied.

"There's one interseting commit - "libata, freezer: avoid block device
removal while system is frozen". It's an ugly hack working around a
deadlock condition between driver core resume and block layer device
removal paths through freezer which was made more reproducible by
writeback being converted to workqueue some releases ago. The bug has
nothing to do with libata but it's just an workaround which is easy to
backport. After discussion, Rafael and I seem to agree that we don't
really need kernel freezables - both kthread and workqueue. There are
few specific workqueues which constitute PM operations and require
freezing, which will be converted to use workqueue_set_max_active()
instead. All other kernel freezer uses are planned to be removed,
followed by the removal of kthread and workqueue freezer support,
hopefully.
Others are device-specific fixes. The most notable is the addition of
NO_NCQ_TRIM which is used to disable queued TRIM commands to Micro
M500 SSDs which otherwise suffers data corruption"

Computing the baud rate register value requires knowledge of the
hardware sampling rate. This information is currently encoded in a baud
rate calculation algorithm ID passed through platform data. However, it
can be derived from the port type directly in most cases.
Compute the sampling rate internally in the driver if the baud rate
calculation algorithm ID isn't specified, and allow platforms to
override the sampling rate through platform data in special cases (this
is only required for SCIFA ports on sh7723 and sh7724, the reason needs
to be investigated).

This patch mondifies charger-manager driver to get temperature of battery
