The option allows you to remove TTY and compile without errors. This
saves space on systems that won't support TTY interfaces anyway.
bloat-o-meter output is below.
The bulk of this patch consists of Kconfig changes adding "depends on
TTY" to various serial devices and similar drivers that require the TTY
layer. Ideally, these dependencies would occur on a common intermediate
symbol such as SERIO, but most drivers "select SERIO" rather than
"depends on SERIO", and "select" does not respect dependencies.
bloat-o-meter output comparing our previous minimal to new minimal by
removing TTY. The list is filtered to not show removed entries with awk
'$3 != "-"' as the list was very long.

All legacy PWM providers have now been moved to the PWM subsystem. The
plan for 3.8 is to adapt all board files to provide a lookup table for
PWM devices in order to get rid of the global namespace. Subsequently,
users of the legacy pwm_request() and pwm_free() functions can be
migrated to the new pwm_get() and pwm_put() functions. Once this has
been completed, the legacy API and the compatibility code in the core
can be removed.
In addition to the above, these changes also add support for configuring
the polarity of a PWM signal (currently only supported on ECAP and
EHRPWM) and include a much needed rework of the i.MX driver. Managed
functions to obtain and release a PWM device (devm_pwm_get() and
devm_pwm_put()) have been added and the pwm-backlight driver has been
updated to use them. If the PWM subsystem hasn't been enabled, dummy
functions are provided that allow the subsystem to safely compile out.
Some common checks on input parameters have been moved to the core and
removed from the drivers. Finally, a small fix corrects the description
of the PWM specifier's second cell in the device tree representation.

"The new PWM subsystem aims at collecting all implementations of the
legacy PWM API and to eventually replace it completely.
The subsystem has been in development for over half a year now and
many drivers have already been converted. It has been in linux-next
for a couple of weeks and there have been no major issues so I think
it is ready for inclusion in your tree."
Arnd Bergmann <arnd@arndb.de>:
"Very much Ack on the new subsystem. It uses the interface
declarations as the previously separate pwm drivers, so nothing
changes for now in the drivers using it, although it enables us to
change those more easily in the future if we want to.
This work is also one of the missing pieces that are required to
eventually build ARM kernels for multiple platforms, which is
currently prohibited (amongs other things) by the fact that you cannot
have more than one driver exporting the pwm functions."

In order to avoid duplicate symbols with legacy PWM API implementations,
the new PWM framework needs to conflict with any of the existing legacy
implementations. This is done in two ways: for implementations provided
by drivers, a conflict is added to the driver to ensure it will have to
be ported to the PWM subsystem before it can coexist with other PWM
providers. For architecture-specific code, the conflict is added to the
PWM symbol to avoid confusion when a previously picked platform or
machine can no longer be selected because of the PWM subsystem being
included.

622 files changed, 28356 insertions(+), 26059 deletions(-)
But, good news is that there is a number of subsystems that moved out of
the staging tree, to their respective "real" portions of the kernel.
Code that moved out was:
- iio core code
- mei driver
- vme core and bridge drivers
There was one broken network driver that moved into staging as a step
before it is removed from the tree (pc300), and there was a few new

- gdm72xx wimax USB driver
- ipack subsystem and 2 drivers

As stated in drivers/mfd/cs5535-mfd.c, the mfd driver exposes the BARs
which then make the GPIO, MFGPT, ACPI, etc. all visible to the system.
So the dependencies of the MFGPT stuff have changed, and most people
expect Kconfig to bring in the necessary dependencies. Without them, the
module fails to load and most people don't understand why because the
details of the rewrite aren't captured anywhere most people who know to
look.
This dependency needs to be reflected in Kconfig.

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.

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

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.

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.

Some current configs turn on GRU for ia64. The GRU code does not
correctly load on boot on ia64 (GRU does continue to work for x86-64), so
changing the IA64 Kconfig to not select GRU on ia64 configs for now until
we have time to fix.

Add a driver for Intersil's ISL29003 ambient light sensor device plus some
documentation. Inspired by tsl2550.c, a driver for a similar device.
It is put in drivers/misc for now until the industrial I/O framework gets
merged.

Add a driver for controlling Dell-specific backlight and rfkill interfaces.
This driver makes use of the dcdbas interface to the Dell firmware to
allow the backlight and rfkill interfaces on Dell systems to be driven
through the standardised sysfs interfaces.

Move x86 platform specific drivers from drivers/misc/
to a new home under drivers/platform/x86/.
The community has been maintaining x86 vendor-specific
platform specific drivers under /drivers/misc/ for a few years.
The oldest ones started life under drivers/acpi.
They moved out of drivers/acpi/ because they don't actually
implement the ACPI specification, but either simply
use ACPI, or implement vendor-specific ACPI extensions.
In the future we anticipate...
drivers/misc/ will go away.
other architectures will create drivers/platform/<arch>

C2port implements a two wire serial communication protocol (bit
banging) designed to enable in-system programming, debugging, and
boundary-scan testing on low pin-count Silicon Labs devices.
Currently this code supports only flash programming through sysfs
interface but extensions shoud be easy to add.

Remove CONFIG_ACPI_EC. It was always set the same as CONFIG_ACPI,
and it had no menu label, so there was no way to set it to anything
other than "y".
Per section 6.5.4 of the ACPI 3.0b specification,
OSPM must make Embedded Controller operation regions, accessed
via the Embedded Controllers described in ECDT, available before
executing any control method.
The ECDT table is optional, but if it is present, the above text
means that the EC it describes is a required part of the ACPI
subsystem, so CONFIG_ACPI_EC=n wouldn't make sense.

Only three of Atmel's AT91 processors (SAM9263, SAM9RL and CAP9) include a

It should therefore only be possible to enable the misc/atmel_pwm.c driver

This patch implements rfkill support for the wireless and bluetooth devices
commonly found on Acer laptops.
For now, we will always poll these devices once a second to guarantee we
can catch state changes. On newer Acer laptops, it may be possible to rely
on WMI events to do this instead, and experimental support for this will be
added in a later patch.
3G has been deliberately left off for now, as we still have no way to
detect it, (nor, AFAIK, has any Linux user tried the code) and on laptops
that don't support 3G, trying to poll for the status will leave the logs
full of ACPI tracebacks.
The old sysfs interface for wireless and bluetooth will be removed in a
later patch.
(Thanks to Henrique de Moraes Holschuh and Dmitry Torokhov for reviewing
this patch).

This is a driver for ACPI extras such as hotkeys and backlight
brightness control on various Panasonic "Let's Note" series laptop
computers.
It exports the backlight via the backlight class device API,
and the hotkeys as input event device. Some more esoteric
items like number of installed batteries are exported via sysfs
device attributes.
Hotkey events also generate old-style ACPI enents through
/proc/acpi/event to interoperate with current versions of acpid.
