Maurus Cuelenaere 62991f7ab3 hwmon: (s3c-hwmon) Depend on S3C_ADC
This way we don't need to modify Kconfig every time a new SoC comes along to
make this driver support it. Also fix some typos while I'm at it.

Jean Delvare bd9fc3a723 Move hdaps driver to platform/x86
The hdaps driver isn't a hardware monitoring driver, so it shouldn't
live under driver/hwmon. drivers/platform/x86 seems much more
appropriate, as the driver is only useful on x86 laptops.

Giel van Schijndel 7721fea3d0 hwmon: f71882fg: add support for the Fintek F71808E
Allow device probing to recognise the Fintek F71808E.

Sysfs interface:
 * Fan/pwm control is the same as for F71889FG
 * Temperature and voltage sensor handling is largely the same as for
   the F71889FG
  - Has one temperature sensor less (doesn't have temp3)
  - Misses one voltage sensor (doesn't have V6, thus in6_input refers to
    what in7_input refers for F71889FG)

For the purpose of the sysfs interface fxxxx_in_temp_attr[] is split up
such that it can largely be reused.

Fenghua Yu cb84b19474 x86, hwmon: Package Level Thermal/Power: pkgtemp hwmon driver
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:

pkgtemp-isa-0000
Adapter: ISA adapter
physical id 0: +33.0°C  (high = +79.0°C, crit = +99.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:      +32.0°C  (high = +79.0°C, crit = +99.0°C)

coretemp-isa-0001
Adapter: ISA adapter
Core 1:      +32.0°C  (high = +79.0°C, crit = +99.0°C)

coretemp-isa-0002
Adapter: ISA adapter
Core 2:      +32.0°C  (high = +79.0°C, crit = +99.0°C)

coretemp-isa-0003
Adapter: ISA adapter
Core 3:      +32.0°C  (high = +79.0°C, crit = +99.0°C)

Jean Delvare cff37c9e82 hwmon: (tmp102) Various fixes
Fixes from my driver review:
http://lists.lm-sensors.org/pipermail/lm-sensors/2010-March/028051.html

Only the small changes are in there, more important changes will come
later separately as time permits.

* Drop the remnants of the now gone detect function
* The TMP102 has no known compatible chip
* Include the right header files
* Clarify why byte swapping of register values is needed
* Strip resolution info bit from temperature register value
* Set cache lifetime to 1/3 second
* Don't arbitrarily reject limit values; clamp as needed
* Make limit writing unconditional
* Don't check for transaction types the driver doesn't use
* Properly check for error when setting configuration
* Report error on failed probe
* Make the driver load automatically where needed
* Various other minor fixes

Steven King beb1b6bbf2 hwmon: Driver for TI TMP102 temperature sensor
Driver for the TI TMP102.

The TI TMP102 is similar to the LM75.  It differs from the LM75 by
having a 16-bit conf register and the temp registers have a minimum
resolution of 12 bits; the extended conf register can select 13-bit
resolution (which this driver does) and also change the update rate
(which this driver currently doesn't use).

[JD: Fix tmp102_exit tag, must be __exit, not __init.]
