Patrick Rudolph 9b8ef11f00 ec/lenovo/h8/acpi: Fix regression (MS Windows crash on boot)
Fix a regression introduced by #21227 0709dc04
(ec/lenovo/h8/acpi/thermal: Add ACPI fan control).

The commit caused Windows to crash as EC reads aren't allowed in the fan
device or it's powerresource's methods. Implement the same approach as all
other platforms using a GNVS variable named FLVL instead of reading from EC.

In addition to EC reads writing to FIELD elements, in another ACPI scope,
seems to be broken. Introduce a new method to set the fan disengage mode.

Tested on Windows 7 and Lenovo T500.

Stefan Ott f63fbdb63a mb/lenovo/x201: Add support for ThinkLight
The thinkpad-acpi driver uses the UCMS (CMOS) ACPI method to control the
ThinkLight from the Operating System. This patch adds partial support for
that method, enough to enable or disable the ThinkLight:

echo on >/proc/acpi/ibm/light
echo off >/proc/acpi/ibm/light

With the original BIOS the UCMS method exposes a wide range of values
through a generic /proc/acpi/ibm/cmos interface. With the changes suggested
in this patch that interface is also exposed but only accepts the commands
to enable or disable the ThinkLight; all other commands are ignored.

This change would potentially benefit all currently supported Thinkpad
models, I only have an X201 available for tests though.

Currently, when using `iasl` 20140926-32 [Oct  1 2014] from Debian 8

ASL 2.0 supports `<<`. For consistency, right now, coreboot still uses
the old syntax. So use `ShiftLeft` instead, which also fixes the build

thinkpad_acpi expects a SSMS method to turn on/off the mute LED
and a MMTS method to turn on/off the microphone mute LED. With
these methods implemented the driver can correctly sync the LEDs
with the corresponding statuses.

There seems to be two different bits to mute the audio in the
Lenovo H8 EC:
 * AMUT, used internally (for example to disable the audio before
    entering S3).
 * ALMT, controllable by the OS, which also toggles the mute LED
    (if present).

Tobias Diedrich 9b798d7904 ec/lenovo/h8: Guard against EC bugs in the battery status logic.
On my Thinkpad with an H8-compatible ENE KB9012 EC (GDHT92WW 1.52), when
the battery is nearly full and we switch from battery to AC by plugging
in the cable, the current rate will not drop to 0 immediately, but the
discharging state is cleared immediately.

This leads to the code trying to process an invalid rate value >0x8000,
leading to a displayed rate of >1000W.

This patch changes the logic to deal with these corner cases.

Nicola Corna f1395d825b ec/lenovo/h8: Add USB Always On
USB AO is the internal name for the dedicated charging port on
ThinkPads when in S3 or lower.

AOEN (bit 0) is internal name for enabling this feature while AOCF
(bits 2 and 3) is the configuration field. According to Peter Stuge,
AOCF can be configured in this way:

    00 => AC S3 S4 S4 USB on, battery S3 USB on, battery S4 S5 off
    11 => AC S3 S4 S4 USB on, battery S3 S4 S5 USB off
    10, 01 => equivalent to 00

This commit also adds a new configuration field in the CMOS of the
X220 and the X201 to activate this feature. It probably can be also
added to all the ThinkPads that support this functionality.

With this functionality USB devices are able to negotiate full power
from the dedicated port (usually the yellow one) even in S3.

Tested on a X201 and X220 with an Android smartphone: with this
feature enabled it shows "Charging" when connected during S3, without
it it shows "Charging slowly" (or it doesn't charge at all on the
X201).

For some reasons the "AC only" mode doesn't work, so it has been
disabled.

Nico Huber 6444b52ce0 Revert "ec/lenovo/h8: don't load configuration when booting from s3"
This reverts commit 83df672d2c.

It's based on the assumption that the H8 keeps its configuration
during a suspend/resume cycle. User reports indicate that this might
not be true.

Caching the settings in a cbtable entry might be a better approach.

Christopher Spinrath b2f9a10c18 ec/lenovo/h8: do not reset volume on s3 wakeup
On s3 wakeup h8_enable is called which resets the (audio) volume. But the
volume should be the same as before the s3 state. In particular, userland
programs (e.g. pulseaudio) may be out of sync, if the volume can be changed
by hardware buttons also emitting acpi events. Hence, do not reset the
volume on s3 wakeup.

Tested on a Lenovo ThinkPad X220.

Timothy Pearson 448e386309 drivers/pc80: Add PS/2 mouse presence detect
On certain Winbond SuperIO devices, when a PS/2 mouse is not
present on the auxiliary channel both channels will cease to
function if the auxiliary channel is probed while the primary
channel is active.  Therefore, knowledge of mouse presence
must be gathered by coreboot during early boot, and used to
enable or disable the auxiliary PS/2 port before control is
passed to the operating system.

Add auxiliary channel PS/2 device presence detect, and update
the Winbond W83667HG-A driver to flag the auxiliary channel as
disabled if no device was detected.
