591ec6509e hwmon: (it87) Check for fan2 and fan3 availability
The fan2 and fan3 input and output pins can be used as GPIOs. Check
their function before exposing their sysfs attributes and accessing
their registers.

The VID input pins can alternatively be used as GPIOs. Make sure we
have at least 4 pins used for VID, otherwise don't bother reading and

6d905e67cf hwmon: (s3c-hwmon) Fix build error
The previous patch, commit be4c23c93c was
from the wrong tree and thus broke the current build which had the
channel configuration name changed.

Fix the following build errors:

drivers/hwmon/s3c-hwmon.c: In function 's3c_hwmon_probe':
drivers/hwmon/s3c-hwmon.c:326: warning: initialization from incompatible pointer type

On newer ASUS boards (e.g. P7P55D) the EC (that - among other things - is

The following patch checks the state of the EC and enable it if needed;
under Linux, native drivers are locked out from ACPI owned resources so
there's no risk of conflict.

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.

a976f150a6 hwmon: applesmc: restore accelerometer and keyboard backlight on resume
On resume from suspend, the driver currently resets the logical state as
if it was brought up from halt.  This patch uses the
dev_pm_ops.resume/restore methods to synchronize the hardware with the

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.

5bed13f580 hwmon-vid: Ignore 6th VID pin of AMD family 0Fh processors
We had a report about a mainboard for AMD family 0Fh processors not
routing the 6th VID pin from the CPU to the hardware monitoring chip.

While the vendor should have wired the pin (or, failing that, should
have hardwired it to level high rather than low), the fact is that
none of these processors are currently known to operate at the lower
voltage levels which require the 6th VID pin. So, as a practical
workaround, I propose to ignore the 6th VID pin for these CPUs.

If this decision ever causes problems, we'll reconsider.

bbe5939ab1 hwmon: (abituguru3) Support multiple DMI strings per chip ID
Most known Abit motherboards have unique uguru chip IDs. However,
some "refresh" boards keep the same chip ID but have a different
DMI string. As our DMI board string matching is (necessarily)
strict, some boards were failing DMI detection, and as the old
probe method was also failing, the driver would not load.

The only known boards affected by this problem are the IP35 Pro XE
(vs IP35 Pro) and the AB9 Pro (vs AB9). Is it not sufficient to
relax the match criteria, as some boards (e.g. the AB9 Quad GT)
have different uguru chip IDs.

This patch replaces the dmi_name string with a NULL terminated
array of strings to be matched per uguru chip ID. It has been
compile and runtime tested (thanks Rune).

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.

Moreover, since commit ef2cfc790b had been

also restores the damages done by this commit concerning the
initialisation/poweroff.

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!

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
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.  :)

have an inverted y axis, we introduce a new macro that special-cases axis
orientation based on two DMI entries: HP dv5 axis configuration is then
based on both the PRODUCT and BOARD name.

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.

ef2cfc790b hp accelerometer: add freefall detection
This adds freefall handling to hp_accel driver.  According to HP, it
should just work, without us having to set the chip up by hand.

hpfall.c is example .c program that parks the disk when accelerometer
detects free fall.  It should work; for now, it uses fixed 20seconds
protection period.

the led and the accelerometer have nothing related.  However, they

other simple to allow to have same loaded at the same time if they are not

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.

058943ddcb hwmon: (abituguru3) Match partial DMI board name strings
The switch-over to using DMI board strings to identify abituguru3 compatible
mainboards works most of the time, but sometimes the vendor has substantially
modified the board string between BIOS revisions.

We have found that the vendor chipset identification string (provided in
brackets) changes frequently and is of no use to us. The rest of the board
string sometimes changes in subtle ways, e.g. whitespace or variations in
capitalization.

The new comparison code checks only a part of the supplied DMI board string,
trimming the bracketed content, whitespace, and ignoring case as necessary.

This fixes a bug where an IP35 Pro running an early BIOS would not be
detected without the force=1 module parameter, and also speculatively
fixes other similiar issues.

Core0 Temp:    +17 C
Core0 Temp:     +3 C
Core1 Temp:    +21 C

being quite below ambient temperature.
There are even reports of negative temperature values.

This patch corrects the temperature reporting of k8temp for

* Legacy ISA drivers (lm78 and w83781d): they only support chips found
  on old designs were ACPI either wasn't supported or didn't deal with

While studying the datasheets for adding F8000 support, I noticed that the

We keep the temp#_alarm attributes as they are, even though it would be more
logical to rename them to temp#_max_alarm. Because lm_sensors v2 depends

ce0bfa5ee2 hwmon: (f71882fg) Fix various sysfs callback function issues
While working on adding F8000 support I noticed that various of the
store sysfs functions (and a few of the show also) had issues.

This patch fixes the following issues in these functions:
* store: storing the result of strto[u]l in an int, resulting in a possible
  overflow before boundary checking
* store: use of f71882fg_update_device(), we don't want to read the whole
  device in store functions, just the registers we need
* store: use of cached register values instead of reading the needed regs
  in the store function, including cases where f71882fg_update_device() was
  not used, this could cause real isues
* show: shown value is a calculation of 2 or more cached register reads,
  without locking the data struct.

This patch is a preparation patch for adding F8000 support to the f71882fg
driver. If you look at the register addresses and esp, the bits used for
the temperature channels, then you will notice that it appears that they
start at 1 in a system meant to start at 0. As the F8000 actually uses the 0
addresses and bits, this patch changes the f71882fg driver to take 4
temperatures numbered 0-3 in to account, using 1-3 in this new scheme for
the temperatures actually present in the F718x2FG.

2e75a4b7ae adt7470: fix pwm at a certain level during temperature sensor scan
In the small window that it takes to read the temperature sensors, the pwm
outputs momentarily drop to 0.  This causes a noticeable hiccup in fan
speed, which is slightly annoying.  The solution is to manually program
the pwm output with whatever the automatic value is and then shift the
fans to manual control while reading temperatures.  Once that is done, put
the fans back to whatever mode of control was there before.

laptops (under the commercial names of "HP Mobile Data Protection System

interfaces as the hdaps and other accelerometer drivers: in sysfs and as
a joystick.

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.

97ae60bb38 hwmon: (lm90) Add support for the LM99 16 degree offset
The LM99 differs from the LM86, LM89 and LM90 in that it reports
remote temperatures (temp2) 16 degrees lower than they really are. So
far we have been cheating and handled this in userspace but it really
should be handled by the driver directly.

ec38fa2b35 hwmon: (lm90) Fix handling of hysteresis value
There are several problems in the way the hysteresis value is handled
by the lm90 driver:

* In show_temphyst(), specific handling of the MAX6646 is missing, so
  the hysteresis is reported incorrectly if the critical temperature
  is over 127 degrees C.
* In set_temphyst(), the new hysteresis register value is written to
  the chip but data->temp_hyst isn't updated accordingly, so there is
  a short period of time (up to 2 seconds) where the old hystereris
  value will be returned while the new one is already active.
* In set_temphyst(), the critical temperature which is used as a base
  to compute the value of the hysteresis register lacks
  device-specific handling. As a result, the value of the hysteresis
  register might be incorrect for the ADT7461 and MAX6646 chips.

Fix these 3 bugs.

8c9398d1e9 hwmon: applesmc: lighter wait mechanism, drastic improvement
The read fail ratio is sensitive to the delay between the first byte
written and the first byte read; apparently the sensors cannot be rushed.
Increasing the minimum wait time, without changing the total wait time,
improves the fail ratio from a 8% chance that any of the sensors fails in
one read, down to 0.4%, on a Macbook Air.  On a Macbook Pro 3,1, the
effect is even more apparent.  By reducing the number of status polls, the
ratio is further improved to below 0.1%.  Finally, increasing the total
wait time brings the fail ratio down to virtually zero.

84d2d7f2ee hwmon: applesmc: fix the 'wait status failed: c != 8' problem
On many Macbooks since mid 2007, the Pro, C2D and Air models, applesmc
fails to read some or all SMC ports.  This problem has various effects,
such as flooded logfiles, malfunctioning temperature sensors,
accelerometers failing to initialize, and difficulties getting backlight
functionality to work properly.

The root of the problem seems to be the command protocol.  The current
code sends out a command byte, then repeatedly polls for an ack before
continuing to send or recieve data.  From experiments leading to this
patch, it seems the command protocol never quite worked or changed so that
one now sends a command byte, waits a little bit, polls for an ack, and if
it fails, repeats the whole thing by sending the command byte again.

This patch implements a send_command function according to the new
interpretation of the protocol, and should work also for earlier models.

Patchset adds separate limit alarms for voltages and temps, it also adds
temp[123]_fault files.  On my Soekris, temps 1,2 are unused/unconnected,
so temp[123]_fault = 1,1,0 respectively.  This agrees with
/usr/bin/sensors, which has always shown them as OPEN.  Temps 4,5,6 are
thermistor based, and dont have a fault bit in their status register.

This patch:

2 different kinds of constants added:
- CHAN_ALM_* constants for (later) vin, temp alarm callbacks.
- CHAN_* conversion constants, used in _init_device, partly for RW1C bits

1b92adaddd hwmon: (lm85) Simplify RANGE_TO_REG
Function RANGE_TO_REG can easily be simplified. Credits go to Herbert
Poetzl for indirectly suggesting this to me. I tested that the new
implementation returns the same result as the original implementation
for all input values.

86010c982d hwmon: (lm85) Select the closest PWM frequency
The LM85 and compatible chips only support 8 arbitrary PWM frequencies.
The algorithm to pick one of them based on the user input is not
optimum. Improve it to always pick the closest supported frequency.

34e7dc6ca4 hwmon: (lm85) Implement the standard PWM frequency interface
Implement the standard PWM frequency interface: pwm[1-*]_freq in
units of 1 Hz, instead of the non-standard pwm[1-*]_auto_pwm_freq
in units of 0.1 Hz. The old naming was not only non-standard, it was
also confusing, because it suggested that the frequency value only
applied in automatic fan speed mode, which isn't true.

810ad7b62c hwmon: (ams) Convert to a new-style i2c driver
The legacy i2c binding model is phasing out, so the ams driver needs
to be converted to a new-style i2c driver. Here is a naive approach of
this conversion. Basically it is moving the i2c device creation from
the ams driver to the i2c-powermac driver. This should work, but I
suspect we could come up with something cleaner by declaring the i2c
device as part of the platform setup. This could be done later by
someone more familiar with openfirmware-based platforms than I am
myself.

One nice thing brought by this conversion is that the ams driver
should be loaded automatically on systems where is is needed (at
least when the I2C interface to the chip is used) providing
coldplug-aware user-space environment.

correctly.  Since this is not always the case, alllow platform code to

configuration registers can be changed after driver initialisation.

49ae6cc800 hwmon: (lm87) Fix masking of config register in lm87_init_client()
lm87_init_client() conditionally sets the Start bit and clears the
INT#_Clear bit in the Config 1 register.  The condition should be that
either of these bits needs changing, but currently it checks the
(self-clearing) Initialization bit instead of INT#_Clear.

Fix the condition and also ensure we never set the Initialization bit.
