This patch adds a hwmon driver for package level thermal control. The driver
dumps package level thermal information through sysfs interface so that upper
level application (e.g. lm_sensor) can retrive the information.
Instead of having the package level hwmon code in coretemp, I write a seperate
driver pkgtemp because:
First, package level thermal sensors include not only sensors for each core,
but also sensors for uncore, memory controller or other components in the
package. Logically it will be clear to have a seperate hwmon driver for package
level hwmon to monitor wider range of sensors in a package. Merging package
thermal driver into core thermal driver doesn't make sense and may mislead.
Secondly, merging the two drivers together may cause coding mess. It's easier
to include various package level sensors info if more sensor information is
implemented. Coretemp code needs to consider a lot of legacy machine cases.
Pkgtemp code only considers platform starting from Sandy Bridge.
On a 1Sx4Cx2T Sandy Bridge platform, lm-sensors dumps the pkgtemp and coretemp:

physical id 0: +33.0°C (high = +79.0°C, crit = +99.0°C)

Now that we have ACPI-based hardware monitoring drivers, and we will
start telling users to use them instead of native drivers when I/O

Also, in the case of monolithic kernels, I think the ACPI drivers
should take precedence over native drivers, so they should be listed

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.

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. :)

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.
