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!

This controller can be found on the D-Link DNS-323 for instance, where
it is to be configured via static i2c_board_info in the board-specific
mach-orion/dns323-setup.c; this driver supports only the new-style
driver model.

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.

12a324b6a3 hp_accel: axis conversion for hp compaq 8710w
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.

72f5de92e1 hwmon: Add LTC4215 driver
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.  :)

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.

137bad3234 lis3lv02d: support both one- and two-byte sensors
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.

9e1c9d8655 hp_accel: do not call ACPI from invalid context
The LED on HP notebooks is connected through ACPI.  That unfortunately
means that it needs to be delayed by using schedule_work() to avoid
calling the ACPI interpreter from an invalid context.

[akpm@linux-foundation.org: use flush_work() rather than sort-of reimplementing it]

9e0c797821 lis3lv02d: merge with leds hp disk
Move the second part of the HP laptop disk protection functionality (a red
led) to the same driver.  From a purely Linux developer's point of view,
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
update the Kconfig text.

c3d6362b87 hwmon: applesmc: fix light sensor readings on newer MacBooks
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.

46a5f173fc hwmon: (abituguru3) Fix CONFIG_DMI=n fallback to probe
When CONFIG_DMI is not enabled, dmi detection should flag that no board
could be detected (err=1) rather than another error condition (err<0).

This fixes the fallback to manual probing for all motherboards, even
those without DMI strings, when CONFIG_DMI=n.
