There is no point in implementing a detect callback for the LTC4215

temperature, the battery temperature and the auxiliary inputs

Currently no alarms are supported, though digital comparators on

Since the auxiliary and battery temperature input scaling depends

We had a report about a mainboard for AMD family 0Fh processors not
routing the 6th VID pin from the CPU to the hardware monitoring chip.
While the vendor should have wired the pin (or, failing that, should
have hardwired it to level high rather than low), the fact is that
none of these processors are currently known to operate at the lower
voltage levels which require the 6th VID pin. So, as a practical
workaround, I propose to ignore the 6th VID pin for these CPUs.

Most known Abit motherboards have unique uguru chip IDs. However,
some "refresh" boards keep the same chip ID but have a different
DMI string. As our DMI board string matching is (necessarily)
strict, some boards were failing DMI detection, and as the old
probe method was also failing, the driver would not load.
The only known boards affected by this problem are the IP35 Pro XE
(vs IP35 Pro) and the AB9 Pro (vs AB9). Is it not sufficient to
relax the match criteria, as some boards (e.g. the AB9 Quad GT)
have different uguru chip IDs.
This patch replaces the dmi_name string with a NULL terminated
array of strings to be matched per uguru chip ID. It has been
compile and runtime tested (thanks Rune).

The LIS302DL accelerometer chip has a 'click' feature which can be used to
detect sudden motion on any of the three axis. Configuration data is
passed via spi platform_data and no action is taken if that's not
specified, so it won't harm any existing platform.
To make the configuration effective, the IRQ lines need to be set up
appropriately. This patch also adds a way to do that from board support
code.
The DD_* definitions were factored out to an own enum because they are
specific to LIS3LV02D devices.

After measurement on my laptop, it seems that turning off the device does
not bring any energy saving (within 0.1W precision). So let's keep the
device always on. It simplifies the code, and it avoids the problem of
reading a wrong value sometimes just after turning the device on.
Moreover, since commit ef2cfc790b had been
too zealous, the device was actually never turned off anyway. This patch
also restores the damages done by this commit concerning the
initialisation/poweroff.

The MSI MS-7031 is based on an ATI IXP300 south bridge. On this south
bridge, accessible I/O ports must be enabled explicitly. Unfortunately
the BIOS forgets to enable access to the hardware monitoring chip I/O

Add a quirk enabling access to the required ports (0x295-0x296). This
is exactly what MSI's own hardware monitoring application is doing, so

Data sheet at:
http://www.sensirion.ch/en/pdf/product_information/Datasheet-humidity-sensor-SHT1x.pdf
These sensors communicate over a 2 wire bus running a device specific
protocol. The complexity of the driver is mainly due to handling the
substantial delays between requesting a reading and the device pulling the
data line low to indicate that the data is available. This is handled by
an interrupt that is disabled under all other conditions.
I wasn't terribly clear on the best way to handle this, so comments on
that aspect would be particularly welcome!
Interpretation of the temperature depends on knowing the supply voltage.
If configured in a board config as a regulator consumer this is obtained
from the regulator subsystem. If not it should be provided in the
platform data.
I've placed this driver in the hwmon subsystem as it is definitely a
device that may be used for hardware monitoring and with it's relatively
slow response times (up to 120 millisecs to get a reading) a caching
strategy certainly seems to make sense!

Asus boards have an ACPI interface for interacting with the hwmon (fan,
temperatures, voltages) subsystem; this driver exposes the relevant
information via the standard sysfs interface.
There are two different ACPI interfaces:
- an old one (based on RVLT/RFAN/RTMP)
- a new one (GGRP/GITM)
Both may be present but there a few cases (my board, sigh) where the
new interface is just an empty stub; the driver defaults to the old one
when both are present.
The old interface has received a considerable testing, but I'm still
awaiting confirmation from my tester that the new one is working as
expected (hence the debug code is still enabled).
Currently all the attributes are read-only, though a (partial) control
should be possible with a bit more work.

I have a laptop HP Compaq 8710W, I compiled into my kernel the LIS3LV02DL
and HP_ACCEL module drivers. While loading it cannot recognize the laptop
model, so i am sending the necessary information to update the database of
axis orientations.
>When the laptop is horizontal the position reported is about 0 for X and Y
>and a positive value for Z
Yes, it is about 0,0,1000, the actual reading says: (-17,-26,1018);
> If the left side is elevated, X increases (becomes positive)
Yes, X goes toward to positive 1000.
>If the front side (where the touchpad is) is elevated, Y decreases (becomes negative)
No, Y goes toward to positive 1000.
>If the laptop is put upside-down, Z becomes negative
Yes, the laptop on a table Z gives 1000, and if upsidedown the Z reads
-1000.
So in few words the Y axis is inverted.

I2C monitoring interface.
I have tested the driver with my board, and it appears to work fine. With
the power supplies disabled, it reads 11.93V input, 1.93V output, no
current and no power. With the supplies enabled, it reads 11.93V input,
11.98V output, no current, no power. I'm not drawing any current at the
moment, so this is reasonable. The value in the sense register never
reads anything except 0, so I expect to get zero from the current and

Sensors responding with 0x3B to WHO_AM_I only have one data register per
direction, thus returning a signed byte from the position which is
occupied by the MSB in sensors responding with 0x3A.
Since multiple sensors share the reply to WHO_AM_I, we rename the defines
to better indicate what they identify (family of single and double
precision sensors).
We support both kind of sensors by checking for the sensor type on init
and defining appropriate data-access routines and sensor limits (for the
joystick) depending on what we find.

Move the second part of the HP laptop disk protection functionality (a red

the led and the accelerometer have nothing related. However, they
correspond to the same ACPI functionality, and so will always be used
together, moreover as they share the same ACPI PNP alias, there is no
other simple to allow to have same loaded at the same time if they are not
in the same module. Also make it requires the led class to compile and

The light sensors ALV0 and ALV1 on newer MacBooks (early 2008 and later)
changed to report 10 bytes instead the earlier 6, and the sensor encoding
subsequently changed. As a result, the reported light sensors readings
are much too low.
Via experiments leading up to this patch, it seems only the ALV0 is
reporting data, and the most useful value therein is a 10-bit big-endian
value at offset 6. This suggests that a new protocol was added as a
backward-compatible replacement on top of the old one.
This patch makes applesmc report the improved light sensor reading for the
new machines, on a scale in conformance with earlier ones.

The switch-over to using DMI board strings to identify abituguru3 compatible
mainboards works most of the time, but sometimes the vendor has substantially
modified the board string between BIOS revisions.
We have found that the vendor chipset identification string (provided in
brackets) changes frequently and is of no use to us. The rest of the board
string sometimes changes in subtle ways, e.g. whitespace or variations in
capitalization.
The new comparison code checks only a part of the supplied DMI board string,
trimming the bracketed content, whitespace, and ignoring case as necessary.
This fixes a bug where an IP35 Pro running an early BIOS would not be
detected without the force=1 module parameter, and also speculatively
fixes other similiar issues.

Check for ACPI resource conflicts in hwmon drivers. I've included
all Super-I/O and PCI drivers.
I've voluntarily left out:
* Vendor-specific drivers: if they conflicted on any system, this would
pretty much mean that they conflict on all systems, and we would know
by now.
* Legacy ISA drivers (lm78 and w83781d): they only support chips found
on old designs were ACPI either wasn't supported or didn't deal with
thermal management.
* Drivers accessing the I/O resources indirectly (e.g. through SMBus):
the checks are already done where they belong, i.e. in the bus drivers.

In the small window that it takes to read the temperature sensors, the pwm
outputs momentarily drop to 0. This causes a noticeable hiccup in fan
speed, which is slightly annoying. The solution is to manually program
the pwm output with whatever the automatic value is and then shift the
fans to manual control while reading temperatures. Once that is done, put
the fans back to whatever mode of control was there before.

New driver to play with. As Jean mentioned a couple of years ago, this
chip is a beast with odd combinations of 8 fans, 4 temperatures, and 13
voltage sensors. This driver has been tested on an IntelliStation Z30.

This adds a driver to the accelerometer sensor found in several HP
laptops (under the commercial names of "HP Mobile Data Protection System
3D" and "HP 3D driveguard"). It tries to have more or less the same
interfaces as the hdaps and other accelerometer drivers: in sysfs and as
a joystick.
This driver was first written by Yan Burman. Eric Piel has updated it
and slimed it up (including the removal of an interface to access to the
free-fall feature of the sensor because it is not reliable enough for
now). Pavel Machek removed few more features and switched locking from
semaphore to mutex.
Several people have contributed to the database of the axes.

It turns out that if one registers a struct platform_device, the
platform device code expects that platform_device.device->driver points
to a struct driver inside a struct platform_driver.
This is not the case with the ipmi-si, ipmi-msghandler and ibmaem
drivers, which causes the suspend/resume hook functions to jump off into
nowhere, causing a crash. Make this assumption hold true for these
three drivers.

As the probable result of zealous copy/pasting, many supported boards
contain sensor names with trailing whitespace. Though this is not a
huge problem, it is inconsistent with other sensor names, and with
other similar hwmon drivers.
Additionally, the DMI nag message added in 2.6.27 was missing a
space between two sentence fragments -- might as well clean that up
too.
Doesn't alter any kernel text, just data.

According to the datasheet voltage is scaled with resistors and
value 192 is nominal voltage. 0 is 0V.

The LM99 differs from the LM86, LM89 and LM90 in that it reports
remote temperatures (temp2) 16 degrees lower than they really are. So
far we have been cheating and handled this in userspace but it really
should be handled by the driver directly.
