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 driver adds support for reading and configuring certain information
on modern HP laptops with WMI BIOS interfaces. It supports enabling and
disabling the ambient light sensor, querying attached displays and hard
drive temperature, sending events on docking and querying the state of the
dock and toggling the state of the wifi, bluetooth and wwan hardware via
rfkill. It also makes the little "(i)" button work on machines that send
that via WMI rather than via the keyboard controller.

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.

Older ThinkPad models do not export some of the hot keys over the
event-based ACPI hot key interface. For these models, one has to poll
the CMOS NVRAM to check the key state at a rate faster than the expected
rate at which the user might repeatedly press the same hot key.
This patch implements this functionality for many of the hotkeys in a
transparent way: hot keys will now Just Work, and the driver knows the
best approach (events or NVRAM polling) to employ, based on the
HKEY.MHKA ACPI method.
Also, the driver can turn off the polling when there are no users for
the hot keys that need such polling.
The NVRAM-based hot keys of the A3x series that have never been
implemented by later models are not supported, to avoid changes in the
keymap of the input devices that could cause headaches in the future.
There is a Kconfig option to avoid compiling the NVRAM polling code, as
it is not very small, and unlikely to be useful on any ThinkPad newer
than a T40, X31 or R52.
This feature is based on a previous effort by Richard Hughes.
