d73772474f thinkpad-acpi: support the second fan on the X61
Support reading the tachometer of the auxiliary fan of a X60/X61.

It was found out by sheer luck, that bit 0 of EC register 0x31
(formely HBRV) selects which fan is active for tachometer readings
through EC 0x84/0x085: 0 for fan1, 1 for fan2.

Many thanks to Christoph Kl??nter, to Whoopie, and to weasel, who
helped confirm that behaviour.

Fan control through EC HFSP applies to both fans equally, regardless
of the state of bit 0 of EC 0x31.  That matches the way the DSDT uses
HFSP.

In order to better support the secondary fan, export a second
tachometer over hwmon, and add defensive measures to make sure we are
reading the correct tachometer.

Support for the second fan is whitelist-based, as I have not found
anything obvious to look for in the DSDT to detect the presence of
the second fan.

d7880f10c5 thinkpad-acpi: forbid the use of HBRV on Lenovo ThinkPads
Forcing thinkpad-acpi to do EC-based brightness control (HBRV) on a
X61 has very... interesting effects, instead of doing nothing (since
it doesn't have EC-based backlight control), it causes "weirdness" in
the fan tachometer readings, for example.

This means the EC register that used to be HBRV has been reused by
Lenovo for something else, but they didn't remove it from the DSDT.

Make sure the documentation reflects this data, and forbid the user
from forcing the driver to access HBRV on Lenovo ThinkPads.

f21179a47f thinkpad-acpi: enhance led support
Add support for extra LEDs on recent ThinkPads, and avoid registering
with the led class the LEDs which are not available for a given
ThinkPad model.

All non-restricted LEDs are always available through the procfs
interface, as the firmware doesn't care if an attempt is made to
access an invalid LED.

b57f7e7b83 thinkpad-acpi: bump up version to 0.23
Plenty of high-profile changes, so it deserves a new version number.

Features added since 0.22:
 *  Restrict unsafe LEDs
 *  New race-less brightness control strategy for IBM ThinkPads
 *  Disclose TGID of driver access from userspace (debug)
 *  Warn when deprecated functions are used

Other changes:
 *  Better debug messages in some subdrivers
 *  Removed "hotkey disable" support, since it breaks the driver
 *  Dropped "ibm-acpi" alias

0e501834f8 thinkpad-acpi: rework brightness support
Refactor and redesign the brightness control backend...

In order to fix bugzilla #11750...

Add a new brightness control mode: support direct NVRAM checkpointing
of the backlight level (i.e. store directly to NVRAM without the need
for UCMS calls), and use that together with the EC-based control.
Disallow UCMS+EC, thus avoiding races with the SMM firmware.

Switch the models that define HBRV (EC Brightness Value) in the DSDT
to the new mode.  These are: T40-T43, R50-R52, R50e, R51e, X31-X41.

Change the default for all other IBM ThinkPads to UCMS-only.  The
Lenovo models already default to UCMS-only.

a4d5effcc7 thinkpad-acpi: restrict access to some firmware LEDs
Some of the ThinkPad LEDs indicate critical conditions that can cause
data loss or cause hardware damage when ignored (e.g. force-ejecting
a powered up bay; ignoring a failing battery, or empty battery; force-
undocking with the dock buses still active, etc).

On almost all ThinkPads, LED access is write-only, and the firmware
usually does fire-and-forget signaling on them, so you effectively
lose whatever message the firmware was trying to convey to the user
when you override the LED state, without any chance to restore it.

Restrict access to all LEDs that can convey important alarms, or that
could mislead the user into incorrectly operating the hardware.  This
will make the Lenovo engineers less unhappy about the whole issue.

Allow users that really want it to still control all LEDs, it is the
unaware user that we have to worry about.

2586d5663d thinkpad-acpi: remove HKEY disable functionality
The HKEY disable functionality basically cripples the entire event
model of the ThinkPad firmware and of the thinkpad-acpi driver.
Remove this functionality from the driver.  HKEY must be enabled at
all times while thinkpad-acpi is loaded, and disabled otherwise.

For sysfs, according to the sysfs ABI and the thinkpad-acpi sysfs
rules of engagement, we will just remove the attributes.  This will be
done in two stages: disable their function now, after two kernel
releases, remove the attributes.

For procfs, we call WARN().  If nothing triggers it, I will simply
remove the enable/disable commands entirely in the future along with
the sysfs attributes.

I don't expect much, if any fallout from this.  There really isn't any
reason to mess with hotkey_enable or with the enable/disable commands
to /proc/acpi/ibm/hotkey, and this has been true for years...

attempting to access the driver.  This is highly useful when dealing

deprecated.

Add a read/write rfkill interface to the bluetooth radio switch on the

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).

b59727965d ACPI: thinkpad-acpi: BIOS backlight mode helper (v2.1)
Lenovo ThinkPads with generic ACPI backlight level control can be easily
set to react to keyboard brightness key presses in a more predictable way
than what they do when in "DOS / bootloader" mode after Linux brings
up the ACPI interface.

The switch to the ACPI backlight mode in the firmware is designed to be
safe to use only as an one way trapdoor.  One is not to force the firmware
to switch back to "DOS/bootloader" mode except by rebooting.  The mode
switch itself is performed by calling any of the ACPI _BCL methods at least
once.

When in ACPI mode, the backlight firmware just issues (standard) events for
the brightness up/down hot key presses along with the non-standard HKEY
events which thinkpad-acpi traps, and doesn't touch the hardware.

thinkpad-acpi will:

1. Place the ThinkPad firmware in ACPI backlight control mode
   if one is available
2. Suppress HKEY backlight change notifications by default
   to avoid double-reporting when ACPI video is loaded when
   the ThinkPad is in ACPI backlight control mode
3. Urge the user to load the ACPI video driver

The user is free to use either the ACPI video driver to get the brightness
key events, or to override the thinkpad-acpi default hotkey mask to get
them from thinkpad-acpi as well (this will result in duplicate events if
ACPI video is loaded, so let's hope distros won't screw this up).

Provided userspace is sane, all should work (and *keep* working), which is
more that can be said about the non-ACPI mode of the new Lenovo ThinkPad
BIOSes when coupled to current userspace and X.org drivers.

Full guidelines for backlight hot key reporting and use of the
thinkpad-acpi backlight interface have been added to the documentation.

A quick study of the 0x5009/0x500A HKEY event on the X61t DSDT revealed the
existence of the EC HTAB register (EC 0x0f, bit 7), and a compare with the
X41t DSDT shows that HKEY.MHKG can be used to verify if the ThinkPad is
tablet-capable (MHKG present), and in tablet mode (bit 3 of MHKG return is
set).

Add an attribute to report this information, "hotkey_tablet_mode".  This
attribute has poll()/select() support, and can be used along with EV_SW
SW_TABLET_MODE to hook userspace to tablet events.

d6ff365577 Documentation - Create laptops sub-directory
There are currently various laptop drivers floating about with no central
place for their documentation, which is currently scattered around the top
level Documentation/ directory.

So, as a first step, lets create a Documentation sub-directory, and update
the relevant index files. The work of then moving the existing laptop
driver related documentation will then be handled later.
