Luca Tettamanti 8d282497cb hwmon: (asus_atk0110) Fix upper limit readings
On newer Asus boards the "upper" limit of a sensor is encoded as
delta from the "lower" limit. Fix the driver to correctly handle
this case.

Daniel Mack 8f3128e714 lis3: add click function
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.

Eric Piel a002ee896d lis3: remove automatic shutdown of the device
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.

Also do more clean up with the usage of the lis3_dev global variable.

Currently we are using separate per model sysfs attr for the 3th pwm, because
the 3th pwm of the f8000 only has automatic mode and not manual mode. Doing
things this way was getting in the way for adding f71858fg support, so this
patch makes the pwm attr identical for all models, and instead adds a check
to store_pwm_enable() disallowing setting the 3th pwm to manual mode
on a f8000 IC.

Jean Delvare 2958b1ec6b hwmon: PCI quirk for hwmon access on MSI MS-7031 board
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
ports, so hardware monitoring fails.

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

Jonathan Cameron 251eb40f5c hwmon: sht15 humidity sensor driver
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!

Luca Tettamanti 2c03d07ad5 hwmon: Add Asus ATK0110 support
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

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.

Add Linux support for the Linear Technology LTC4215 Hot Swap controller
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
power calculations.

I didn't attempt to support changing any of the chip's settings or
enabling the FET.  I'm not sure even how to do that and still fit within
the hwmon framework.  :)

Pavel Machek be84cfc588 hp_accel: adev is poor name of exported symbol
As Andrew noted, adev is pretty poor name for symbol being exported.
Rename it to lis3.

Jean Delvare e7a19c5624 dmi: Let dmi_walk() users pass private data
At the moment, dmi_walk() lacks flexibility, users can't pass data to
the callback function. Add a pointer for private data to make this
function more flexible.

Jean Delvare fb4504fe84 Move the pcf8591 driver to hwmon
Directory drivers/i2c/chips is going away, so drivers there must find
new homes. For the pcf8591 driver, the best choice seems to be the
hwmon subsystem. While the Philips PCF8591 device isn't a typical
hardware monitoring chip, its DAC interface is compatible with the
hwmon one, so it fits somewhat.

If a better subsystem is ever created for ADC/DAC chips, the driver
could be moved there.

Gong Jun a157d06d4d hwmon: (w83627ehf) Only expose in6 or temp3 on the W83667HG
The pin for in6 and temp3 is shared on the W83667HG, so only one of
these features can be supported on any given system. Let the driver
select which one depending on the temp3 disabled bit.

Gong Jun 237c8d2f54 hwmon: (w83627ehf) Add support for W83667HG
Add initial support for the Nuvoton W83667HG chip to the w83627ehf
driver. It has been tested on ASUS P5QL PRO by Gong Jun.

At the moment there is still a usability issue which is that only in6
or temp3 can be present on the W83667HG, so the driver shouldn't
expose both. This will be addressed later.
