Currently, we use hard code number to verify if we are in the
arp_interval timeslice. But some user may want to reduce/extend
the verify timeslice. With the similar team option 'missed_max'
the uers could change that number based on their own environment.

CAPTURE buffers might be read by the hardware after they are dequeued,
which goes against the general idea that userspace has full control over
dequeued buffers. Explain why and document the restrictions that this
implies for userspace.

ARC processors are supported in upstream kernel since v3.9
and so far there was no documentation about them except some
Device Tree bindings.
Fixing it with the simples set of docs now:
1. Overview with pointers to other informational resources
2. Autogenerated feature table
Note though it's just the very beginning, there will be more
for sure given time as there're many things worth documenting
and in fact even contents itself is avaialble but just spread
in some other places. Now we'll try to keep all here and
then maintain it looking forward to match the state of development.

When converting the thermal-zones bindings to yaml the definition of the
contribution property changed. The intention is the same, an integer
value expressing a ratio of a sum on how much cooling is provided by the
device to the zone. But after the conversion the integer value is
limited to the range 0 to 100 and expressed as a percentage.
This is problematic for two reasons.
- This do not match how the binding is used. Out of the 18 files that
make use of the property only two (ste-dbx5x0.dtsi and
ste-hrefv60plus.dtsi) sets it at a value that satisfy the binding,
100. The remaining 16 files set the value higher and fail to validate.
- Expressing the value as a percentage instead of a ratio of the sum is
confusing as there is nothing to enforce the sum in the zone is not
greater then 100.
This patch restore the pre yaml conversion description and removes the
value limitation allowing the usage of the bindings to validate.

The BAM Data Multiplexer provides access to the network data channels of
modems integrated into many older Qualcomm SoCs, e.g. Qualcomm MSM8916 or
MSM8974. It is built using a simple protocol layer on top of a DMA engine
(Qualcomm BAM) and bidirectional interrupts to coordinate power control.
The device tree node combines the incoming interrupt with the outgoing
interrupts (smem-states) as well as the two DMA channels, which allows
the BAM-DMUX driver to request all necessary resources.

We've got a bug report about the non-working keyboard on ASUS ZenBook
UX425UA. It seems that the PS/2 device isn't ready immediately at
boot but takes some seconds to get ready. Until now, the only
workaround is to defer the probe, but it's available only when the
driver is a module. However, many distros, including openSUSE as in
the original report, build the PS/2 input drivers into kernel, hence
it won't work easily.
This patch adds the support for the deferred probe for i8042 stuff as
a workaround of the problem above. When the deferred probe mode is
enabled and the device couldn't be probed, it'll be repeated with the
standard deferred probe mechanism.
The deferred probe mode is enabled either via the new option
i8042.probe_defer or via the quirk table entry. As of this patch, the
quirk table contains only ASUS ZenBook UX425UA.
The deferred probe part is based on Fabio's initial work.

The FPGA region class driver data structure is being treated as a
managed resource instead of using the standard dev_release call-back
function to release the class data structure. This change removes the
managed resource code and combines the create() and register()
functions into a single register() or register_full() function.
The register_full() function accepts an info data structure to provide
flexibility in passing optional parameters. The register() function
supports the current parameter list for users that don't require the
use of optional parameters.
