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.

We expect to follow this naming convention (vmw_<module_name>) for all

VMware, with the sole exception of vmxnet3 driver (since the name of
mainline driver happens to match with the name used in VMware Tools).

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.

OSPM must make Embedded Controller operation regions, accessed

The ECDT table is optional, but if it is present, the above text

Only three of Atmel's AT91 processors (SAM9263, SAM9RL and CAP9) include a
PWM controller.
It should therefore only be possible to enable the misc/atmel_pwm.c driver
on those processors (and not all AT91 processors).

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.

Add a read/write rfkill interface to the bluetooth radio switch on the
bluetooth submodule, and one for the wireless wan radio switch to the wan
submodule.
Since rfkill does care for when a switch changes state, use WLSW
notifications to also check if the WWAN or Bluetooth switches did not
change state (due to them being slaves of WLSW in firmware/hardware, but
that reality not being always properly exported by the thinkpad firmware).

Add additional capabilities to the Fujitsu-laptop driver.
* Brightness hotkey actions are sent to userspace. This can be disabled
using a module parameter if it causes issues with models which handle
these keys transparently in the BIOS.
* Actions of additional hotkeys found on some Fujitsu models (eg: the
suspend key and the dedicated "power on passphrase" keys) are broadcast
to userspace.
* An alternative brightness control method used by some Fujitsu models
(for example, the S6410) is now supported, enabling software brightness
controls on models using this method.
* DMI-based module aliases are configured for the S6410 and S7020.
* The current LCD brightness after booting should now be reflected in the
standard backlight interface sysfs file (previously it was always set to
0). The platform brightness sysfs interface has always been fine.
Thanks go to Peter Gruber who provided a significant portion of this code
and tested various iterations of the patch on his S6410.

Clocksource and clockevent device based on the Atmel TC blocks.
The clockevent device handles both periodic and oneshot modes, so this
enables NO_HZ and high res timers on some platforms that previously
couldn't use those mechanisms.
This works on both AVR32 and AT91 chips, given relevant patches for
tclib support (always) and clockevents (or else this will only look
like a higher precision clocksource). It's an updated and modularized
version of an AT91-only patch that has circulated for some time now.
Changes relative to the original patch:
* Update to use new tclib API
* Replace open-coded do-while loop using goto with a real do-while loop
* Minor irq handler optimization: Load register base address from
dev_id instead of a global variable.
* Aggressively turn off clocks when the clockevent isn't being used
* Include the clockevent code on AT91RM9200 as well. The rating is
lower than the System Timer, so the clock will usually stay off.
* Don't assume that the number of clocks is always equal to the
number of irqs.

Create <linux/atmel_tc.h> based on <asm-arm/arch-at91/at91-tc.h> and the
at91sam9263 and at32ap7000 datasheets. Most AT91 and AT32 SOCs have one
or two of these TC blocks, which include three 16-bit timers that can be
interconnected in various ways.
These TC blocks can be used for external interfacing (such as PWM and
measurement), or used as somewhat quirky sixteen-bit timers.
Changes relative to the original version:
* Drop unneeded inclusion of <linux/mutex.h>
* Support an arbitrary number of TC blocks
* Return a struct with information about a TC block from
atmel_tc_alloc() instead of using a combination of return values
and "out" parameters.
* ioremap() the I/O registers on allocation
* Look up clocks and irqs for all channels
* Add "name" parameter to atmel_tc_alloc() and use this when
requesting the iomem resource.
* Check if the platform provided the necessary resources at probe()
time instead of when the TCB is allocated.

It is safe for these Kconfig entries to use select because
they select ACPI_WMI, which already has its dependencies
satisfied. This makes Kconfig more user friendly, since
the user selects the driver they want and the dependency
is met for them. Otherwise, the user would have to find
and enable ACPI_WMI to make enabling these drivers possible.
