      ACPI: remove CONFIG_ACPI_EC · 8950d89a
      由 Bjorn Helgaas 提交于 
      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.

      acer-wmi: Add rfkill support for wireless and bluetooth · 0606e1ab
      由 Carlos Corbacho 提交于 
      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).

      HP iLO driver · 89bcb05d
      由 David Altobelli 提交于 
      A driver for the HP iLO/iLO2 management processor, which allows userspace
programs to query the management processor.  Programs can open a channel
to the device (/dev/hpilo/dXccbN), and use this to send/receive queries.  
The O_EXCL open flag is used to indicate that a particular channel cannot
be shared between processes.  This driver will replace various packages
HP has shipped, including hprsm and hp-ilo.

      ACPI: thinkpad-acpi: add bluetooth and WWAN rfkill support · 0e74dc26
      由 Henrique de Moraes Holschuh 提交于 
      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).

      Fujitsu-laptop update · 20b93734
      由 Jonathan Woithe 提交于 
      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.

      misc,acpi,backlight: compal Laptop Extras · 5411552c
      由 Cezary Jackiewicz 提交于 
      This is driver for Compal Laptop: FL90/IFL90, based on MSI driver.

This driver exports a few files in /sys/devices/platform/compal-laptop/:
 lcd_level - screen brightness: contains a single integer in the range 0..7 (rw)
 wlan - wlan subsystem state: contains 0 or 1 (rw)
 bluetooth - bluetooth subsystem state: contains 0 or 1 (rw)
 raw - raw value taken from embedded controller register (ro)

In addition to these platform device attributes the driver registers itself
in the Linux backlight control subsystem and is available to userspace under
/sys/class/backlight/compal-laptop/.

      atmel_tc clocksource/clockevent code · 4d243f92
      由 David Brownell 提交于 
      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.

      atmel_tc library · 2a341f5c
      由 David Brownell 提交于 
      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.
