e7ae1e7ef9 ACER_WMI/ASUS_LAPTOP: fix build bug
randconfig testing in x86.git found the following upstream build bug:

 drivers/built-in.o: In function `acer_led_exit':
 acer-wmi.c:(.text+0xdc76e): undefined reference to `led_classdev_unregister'
 drivers/built-in.o: In function `acer_platform_probe':
 acer-wmi.c:(.devinit.text+0x63e6): undefined reference to `led_classdev_register'

which was due to acer-wmi.o only depending on CONFIG_LEDS_CLASS, while
also using a symbol offered by CONFIG_NEW_LEDS. Also fix a similar bug
in CONFIG_ASUS_LAPTOP.

3f6cb5630a ACPI: thinkpad-acpi: fix selects in Kconfig
Add missing select for BACKLIGHT_LCD_SUPPORT, as select doesn't select the
dependencies of a symbol for us.

Also, "select INPUT" in Kconfig.  We are not an Input device, nor are we
anywhere close to the input subsystem in the Kconfig tree, so using
"depends on INPUT" is not user-friendly at all.

4d243f92e4 atmel_tc clocksource/clockevent code
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.

2a341f5cf5 atmel_tc library
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.

d7c1d17dfe ACPI: thinkpad-acpi: make the video output feature optional
The video output port control feature is not very useful on many ThinkPads
(especially when a X server is running), and lately userspace is getting
better and better at it, so it makes sense to allow users to stripe out the
thinkpad-acpi video feature from their kernels and save at least 2KB.

4a507d93fa acer-wmi, tc1100-wmi: select ACPI_WMI
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.

01e88f2598 ACPI: thinkpad-acpi: add CMOS NVRAM polling for hot keys (v9)
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.

ff80f1370f ACPI: thinkpad-acpi: revert new 2.6.23 CONFIG_THINKPAD_ACPI_INPUT_ENABLED option
Revert new 2.6.23 CONFIG_THINKPAD_ACPI_INPUT_ENABLED Kconfig option because
it would create a legacy we don't want to support.

CONFIG_THINKPAD_ACPI_INPUT_ENABLED was added to try to fix an issue that is
now moot with the addition of the netlink ACPI event report interface to
the ACPI core.

Now that ACPI core can send events over netlink, we can use a different
strategy to keep backwards compatibility with older userspace, without the
need for the CONFIG_THINKPAD_ACPI_INPUT_ENABLED games.  And it arrived
before CONFIG_THINKPAD_ACPI_INPUT_ENABLED made it to a stable mainline
kernel, even, which is Good.

This patch is in sync with some changes to thinkpad-acpi backports, that
will keep things sane for userspace across different combinations of kernel
versions, thinkpad-acpi backports (or the lack thereof), and userspace
capabilities:

Unless a module parameter is used, thinkpad-acpi will now behave in such a
way that it will work well (by default) with userspace that still uses only
the old ACPI procfs event interface and doesn't care for thinkpad-acpi
input devices.

It will also always work well with userspace that has been updated to use
both the thinkpad-acpi input devices, and ACPI core netlink event
interface, regardless of any module parameter.

The module parameter was added to allow thinkpad-acpi to work with
userspace that has been partially updated to use thinkpad-acpi input
devices, but not the new ACPI core netlink event interface.  To use this
mode of hot key reporting, one has to specify the hotkey_report_mode=2
module parameter.

The thinkpad-acpi driver exports the value of hotkey_report_mode through
sysfs, as well.  thinkpad-acpi backports to older kernels, that do not
support the new ACPI core netlink interface, have code to allow userspace
to switch hotkey_report_mode at runtime through sysfs.  This capability
will not be provided in mainline thinkpad-acpi as it is not needed there.

So, rework the help text, and change the default to N.  Note that

24d3b77467 ACPI: thinkpad-acpi: allow use of CMOS NVRAM for brightness control
It appears that Lenovo decided to break the EC brightness control interface
in a weird way in their latest BIOSes.  Fortunately, the old CMOS NVRAM
interface works just fine in such BIOSes.

Add a module parameter that allows the user to select which strategy to use
for brightness control: EC, NVRAM, or both.  By default, do both (which is
the way thinkpad-acpi used to work until now) on IBM ThinkPads, and use
NVRAM only on Lenovo ThinkPads.

1a343760b5 ACPI: thinkpad-acpi: make the input event mode the default
Make the input layer the default way to deal with thinkpad-acpi hot keys,
but add a kernel config option to retain the old way of doing things.

This means we map a lot more keys to useful stuff by default, and also that
we enable hot key handling by default on driver load (like Windows does).

The documentation for proper use of this resource is also updated.

IBMASM: must depend on CONFIG_INPUT

The driver registers couple of input devices and therefore must depend
on CONFIG_INPUT.

This config symbol name is confusing and unneeded/unwanted, so just
change it to MISC_DEVICES.

376df37a5b Use menuconfig objects II - misc strange dev
Make a "menuconfig" out of the Kconfig objects "menu, ..., endmenu",
so that the user can disable all the options in that menu at once
instead of having to disable each option separately.

2bcb1b7de9 Remove the blink driver
Yeah, we could have just disabled it, but there's work on a new one that
isn't as fundamentally broken, so there really doesn't seem to be any
point in keeping it around.

The recent timer cleanup broke the only valid use, and when I say
"valid", I obviously mean "totally broken".  So it's not like it works,
or really even can work in the current format that uses the unsafe
"panic" LED blinking routines..
