This driver allows userspace to access the data processing FPGAs on the
OVRO CARMA board. It has two modes of operation:1) random access
This allows users to poke any DATA-FPGA registers by using mmap to map
the address region directly into their memory map.2) correlation dumping
When correlating, the DATA-FPGA's have special requirements for getting
the data out of their memory before the next correlation. This nominally
happens at 64Hz (every 15.625ms). If the data is not dumped before the
next correlation, data is lost.The data dumping driver handles buffering up to 1 second worth of
correlation data from the FPGAs. This lowers the realtime scheduling
requirements for the userspace process reading the device.Signed-off-by: Ira W. Snyder

The PTI (Parallel Trace Interface) driver directs
trace data routed from various parts in the system out
through an Intel Penwell PTI port and out of the mobile
device for analysis with a debugging tool (Lauterbach or Fido).
Though n_tracesink and n_tracerouter line discipline drivers
are used to extract modem tracing data to the PTI driver
and other parts of an Intel mobile solution, the PTI driver
can be used independent of n_tracesink and n_tracerouter.You should select this driver if the target kernel is meant for
an Intel Atom (non-netbook) mobile device containing a MIPI
P1149.7 standard implementation.Signed-off-by: J Freyensee

Packet hub driver of Topcliff PCH
Topcliff PCH is the platform controller hub that is going to be used in
Intel's upcoming general embedded platform. All IO peripherals in
Topcliff PCH are actually devices sitting on AMBA bus. Packet hub is
a special converter device in Topcliff PCH that translate AMBA transactions
to PCI Express transactions and vice versa. Thus packet hub helps present
all IO peripherals in Topcliff PCH as PCIE devices to IA system.
Topcliff PCH has MAC address and Option ROM data.
These data are in SROM which is connected to PCIE bus.
Packet hub driver of Topcliff PCH can access MAC address and Option ROM data in
SROM via sysfs interface.Signed-off-by: Greg Kroah-Hartman

In an effort to minimize customer confusion we want to unify naming
convention for VMware-provided kernel modules. This change renames the
balloon driver from vmware_ballon to vmw_balloon.We expect to follow this naming convention (vmw_) for all
modules that are part of mainline kernel and/or being distributed by
VMware, with the sole exception of vmxnet3 driver (since the name of
mainline driver happens to match with the name used in VMware Tools).Signed-off-by: Dmitry Torokhov

This driver adds support for the BMP085 digital pressure sensor from Bosch
Sensortec. It exposes a sysfs api to userspace where pressure and
temperature measurement results can be read from the pressure0_input and
temp0_input file. The chip is able to calculate the average of up to
eight samples to increase the accuracy. This feature can be controlled by
writing to the oversampling file.The BMP085 digital pressure sensor can measure ambient air pressure and
temperature. Both values can be obtained from sysfs files. The pressure
is measured by reading from pressure0_input. Valid values range from
30000 to 110000 pascal with a resolution of 1 pascal (=0.01 millibar).temp0_input holds the current temperature in degree celsius, multiplied by
10. This results in a resolution of a tenth degree celsius. Values range
from -400 to 850.To increase the accuracy, this chip can calculate the average of 1, 2, 4
or 8 samples. This behavior is controlled through the oversampling sysfs
file. Two to the power of the value written to that file specifies how
many samples will be used. Valid values: 0..3.[akpm@linux-foundation.org: fix typo]

This is a standalone version of VMware Balloon driver. Ballooning is a
technique that allows hypervisor dynamically limit the amount of memory
available to the guest (with guest cooperation). In the overcommit
scenario, when hypervisor set detects that it needs to shuffle some
memory, it instructs the driver to allocate certain number of pages, and
the underlying memory gets returned to the hypervisor. Later hypervisor
may return memory to the guest by reattaching memory to the pageframes and
instructing the driver to "deflate" balloon.We are submitting a standalone driver because KVM maintainer (Avi Kivity)
expressed opinion (rightly) that our transport does not fit well into
virtqueue paradigm and thus it does not make much sense to integrate with
virtio.There were also some concerns whether current ballooning technique is the
right thing. If there appears a better framework to achieve this we are
prepared to evaluate and switch to using it, but in the meantime we'd like
to get this driver upstream.We want to get the driver accepted in distributions so that users do not
have to deal with an out-of-tree module and many distributions have
"upstream first" requirement.The driver has been shipping for a number of years and users running on
VMware platform will have it installed as part of VMware Tools even if it
will not come from a distribution, thus there should not be additional
risk in pulling the driver into mainline. The driver will only activate
if host is VMware so everyone else should not be affected at all.Signed-off-by: Dmitry Torokhov

This is based on the old code on arch/x86/kernel/mfgpt_32.c, except it's
not x86 specific, it's modular, and it makes use of a PCI BAR rather than
a random MSR. Currently module unloading is not supported; it's uncertain
whether or not it can be made work with the hardware.[akpm@linux-foundation.org: add X86 dependency]
