Guenter Roeck dc92cd0c13 hwmon: (ina2xx) Add support for INA220 and INA230
INA220 is register compatible to INA219, and INA230 is register compatible to
INA226, so all we need to do is to add name aliases for those two chips.

Vivien Didelot 6c1fe725fd hwmon: add Maxim MAX197 support
The MAX197 is an A/D converter, made by Maxim. This driver currently
supports the MAX197, and MAX199. They are both 8-Channel, Multi-Range,
5V, 12-Bit DAS with 8+4 Bus Interface and Fault Protection.

The available ranges for the MAX197 are {0,-5V} to 5V, and {0,-10V} to
10V, while they are {0,-2V} to 2V, and {0,-4V} to 4V on the MAX199.

sensor. The following functionality has been implemented:

  * get current temperature
  * get/set minimum, maximum and critical temperature
  * get/set hysteresis
  * get alarm events for minimum, maximum and critical temperature

All implemented sysfs attributes have been sucessfully tested at temperatures
of 15°C to 40°C.

Iain Paton 27f8b13555 hwmon: Honeywell Humidicon HIH-6130/HIH-6131 humidity and temperature sensor driver
This is a new driver for the Honeywell Humidicon HIH-6130/HIH-6131 humidity sensor.

The driver is based on the existing Sensiron sht21 driver with the necessary changes
to the probe, update_measurements and conversion functions necessary to use the
Honeywell sensors.

There's no difference between the 6130 & 6131 other than the 6131 having an external
condensation filter attached.

Hans de Goede 312869ec93 hwmon: (sch56xx) Add support for the integrated watchdog (v2)
Add support for the watchdog integrated into the SMSC SCH5627 and
SCH5636 superio-s. Since the watchdog is part of the hwmon logical device
and thus shares ioports with it, the watchdog driver is integrated into the
existing hwmon drivers for these.

Note that this version of the watchdog support for sch56xx superio-s
implements the watchdog chardev interface itself, rather then relying on
the recently added watchdog core / watchdog_dev. This is done because
currently some needed functionality is missing from watchdog_dev, as soon
as this functionality is added (which is being discussed on the
linux-watchdog mailinglist), I'll convert this driver over to using
watchdog_dev.

Guenter Roeck f4af6fd6e2 hwmon: (coretemp) Don't use threshold registers for tempX_max
With commit c814a4c7c4, the meaning of tempX_max
was changed. It no longer returns the value of bits 8:15 of
MSR_IA32_TEMPERATURE_TARGET, but instead returns the value of CPU threshold
register T1. tempX_max_hyst was added to reflect the value of temperature
threshold register T0.

As it turns out, T0 and T1 are used on some systems, presumably by the BIOS.
Also, T0 and T1 don't have a well defined meaning. The thresholds may be used
as upper or lower limits, and it is not guaranteed that T0 <= T1. Thus, the new
attribute mapping does not reflect the actual usage of the threshold registers.
Also, register contents are changed during runtime by an entity other than the
hwmon driver, meaning the values cached by the driver do not reflect actual
register contents.

Revert most of c814a4c7c4 to address the problem.
Support for T0 and T1 will be added back in with a separate commit, using new
attribute names.

Add support for NTC Thermistor series. In this release, the
following thermistors are supported: NCP15WB473, NCP18WB473, NCP03WB473,
and NCP15WL333. This driver is based on the datasheet of MURATA.

The driver in the patch does conversion from the raw ADC value
(either voltage or resistence) to temperature. In order to use
voltage values as input, the circuit schematics should be provided
with the platform data. A compensation table for each type of thermistor
is provided for the conversion.

This patch adds a new driver for SMSC SCH5636 Super I/O chips.
The chips include an embedded microcontroller for hardware monitoring
solutions, allowing motherboard manufacturers to create their own
custom hwmon solution based upon the SCH5636.

Currently the sch5636 driver only supports the Fujitsu Theseus SCH5636
based hwmon solution. The sch5636 driver runs a sanity check on
loading to ensure it is dealing with a Fujitsu Theseus and not with
another custom SCH5636 based hwmon solution.

Hans de Goede 3cad402281 hwmon/f71882fg: Add support for f71889ed
Note that this patch also makes 2 changes to the code paths for the f71889fg
to keep the code unified between the 2 (for simplicities sake). Both of these
are harmless for then f71889fg:

1) The first change is to always set the FAN_PROG_SEL bit to 0. This influences
   accesses to some banked fan / pwm registers. On the f71889fg no registers
   which we use are banked. On the f71889ed however some more fan registers
   have been banked including one which we use, by making the FAN_PROG_SEL bit
   0, address 0x96 will point to the right register.
2) The second change is to see a FANx_TEMP_SEL value of 0 as pointing to
   a PECI / AMDSI value, and thus disable our pwm related sysfs attr.
   This is correct for the f71889ed and on the f71889fg 0 is a reserved
   value, so we should never see it and if we do, disabling the pwm related
   sysfs attr is a sane thing to do.

Add support for exposing all GPIO pins as analog voltages. Though this is
not an ideal use of the chip, some hardware engineers may decide that the
LTC4245 meets their design requirements when studying the datasheet.

The GPIO pins are sampled in round-robin fashion, meaning that a slow
reader will see stale data. A userspace application can detect this,
because it will get -EAGAIN when reading from a sysfs file which contains
stale data.

Users can choose to use this feature on a per-chip basis by using either
platform data or the OF device tree (where applicable).

Below you will find an updated version from the original series bunching all patches into one big patch
updating broken web addresses that are located in Documentation/*
Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult,
the best way to deal with these is to use web.archive.org to locate these addresses that are outdated.
Now there are also some addresses pointing to .spec files some are located, but some(after searching
on the companies site)where still no where to be found. In this case I just changed the address
to the company site this way the users can contact the company and they can locate them for the users.

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

* 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

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).

Jean Delvare 2d2a7cff1b ltc4215/ltc4245: Discard obsolete detect methods
There is no point in implementing a detect callback for the LTC4215
and LTC4245, as these devices can't be detected. It was there solely
to handle "force" module parameters to instantiate devices, but now
we have a better sysfs interface that can do the same.

So we can get rid of the ugly module parameters and the detect
callbacks. This shrinks the binary module sizes by 36% and 46%,
respectively.

Improve the example code to be at least useable, as in not causing
harm (as shown below). Code can still be improved further, but this
adds some basic safeguards.

1. hpfall *MUST* mlockall(MCL_CURRENT|MCL_FUTURE); itself!
Since the Program sits and waits most of the time it becomes very likely
swapped out. If it gets woken up when the laptop drops from the table
while it is swapped out it actually triggers harddrive activity!

2. Daemonize hpfall using 'daemon(0,0)' (quick and dirty).

3. Give hpfall realtime priority.
Should give a chance that it has less latency when woken up.

This driver exposes ACPI 4.0 compliant power meters as hardware monitoring
devices.  This second revision of the driver also exports the ACPI string
info as sysfs attributes, a list of the devices that the meter measures,
and will send ACPI notifications over the ACPI netlink socket.  This
latest revision only enables the power capping controls if it can be
confirmed that the power cap can be enforced by the hardware and explains
how the notification interfaces work.

Mark Brown 08bad5a821 hwmon: WM831x PMIC hardware monitoring driver
This driver adds support for the hardware monitoring features of
the WM831x PMICs to the hwmon API. Monitoring is provided for
the system voltages supported natively by the WM831x, the chip
temperature, the battery temperature and the auxiliary inputs
of the WM831x.

Currently no alarms are supported, though digital comparators on
the WM831x devices would allow these to be provided.

Since the auxiliary and battery temperature input scaling depends
on the system configuration the value is reported as a voltage to
userspace.

Ira Snyder 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.  :)

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.

Manuel Lauss c8ac32e471 hwmon: (lm70) Add TI TMP121 support
The Texas Instruments TMP121 is a SPI temperature sensor very similar
to the LM70, with slightly higher resolution.  This patch extends the
LM70 driver to support the TMP121.  The TMP123 differs in pin assign-
ment.

Kaiwan N Billimoria 2b7300513b hwmon: (lm70) Code streamlining and cleanup
This fixes a byteswap bug in the LM70 temperature sensor driver,
which was previously covered up by a converse bug in the driver
for the LM70EVAL-LLP board (which is also fixed).

Other fixes:  doc updates, remove an annoying msleep(), and improve
three-wire protocol handling.
