Hans de Goede 4901062f78 hwmon: (f71882fg) Add missing pwm3 attr for f71862fg
For some reason the fan_attr array for the f71862fg was missing the attr for
the 3th pwm output. This patch fixes this.

Hans de Goede 754a5907b0 hwmon: (f71882fg) Separate max and crit alarm and beep
While studying the datasheets for adding F8000 support, I noticed that the
F718x2 has separate alarms (and beep control) for its max and crit limits.

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
on them.

Hans de Goede bc27490f91 hwmon: (f71882fg) Cleanup fan and temp hyst functions
Simplify fan and temp hyst. handling by treating the registers as an array of
nibbles instead of using switch cases. Also unify the way hysts are handled
between temp and fans, the temp code was storing the actual per temp hyst
values in 4 u8's, where as the fan code was storing actual register values.

Hans de Goede 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.

Hans de Goede 7567a04355 hwmon: (f71882fg) Prepare for adding F8000 support
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.

It turns out that the adt7470's automatic fan control algorithm only works

someone tells the chip to read its temperature sensors.  Regrettably, this

The adt7470 driver currently assumes that 1s is the proper time to wait to

sensors and then lowers it based on the number of sensor inputs that have
nozero values.

Darrick J. Wong 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.

Pavel Machek 455fbdd376 LIS3LV02Dx Accelerometer driver
This adds a driver to the accelerometer sensor found in several HP
laptops (under the commercial names of "HP Mobile Data Protection System
3D" and "HP 3D driveguard").  It tries to have more or less the same
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.

  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.

Henrik Rydberg 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.

Henrik Rydberg 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.

Bring hwmon/pc87360 into agreement with
Documentation/hwmon/sysfs-interface.

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

Jean Delvare 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.

interface number we're looking for is higher than the number of
interfaces that AEM claims to have, stop probing.

Alistair John Strachan 4ef664b5bc abituguru3: prefer DMI probing to manual probing
Previously the driver was only using DMI to prevent smbus probing on
non-Abit motherboards.  However, since the manual probing method is
brittle and prone to failure on some Abit motherboards (esp.  the Abit
IP35 Pro) it is better to use DMI to also read the board name and then
decide whether or not to probe the bus.

At the moment, we do not have a list of valid DMI name strings to use
for existing and supported motherboards.  This patch only implements DMI
probing for the IP35 Pro.  For motherboards that can not yet use DMI
probing, a warning will be printed to the kernel log asking those users
to email me their dmidecode output.

The existing manual probing mechanism will be used if CONFIG_DMI is not
enabled, if DMI probing fails (for DMI-unsupported motherboards), or if
DMI probing fails and the "force" option is set (for DMI-supported
motherboards).  Ideally in the longer term this manual probing method
would be removed.

This patch should be safe to apply as it does not change the probing
behaviour for most of the supported motherboards, just the IP35 Pro,
which already has regressions filed against it in 2.6.26.

that useful. It was dropped from the Linux 2.4 version of this driver
back in July 2004.

The only users who have reported that they were still using this
parameter, needed it to switch the chip from automatic fan speed
control back to manual mode. Now that the driver creates pwmN_enable
sysfs files, users will be able to use these files instead, which is
way less agressive.

In set_pwm_auto_pwm_minctl, we write cached register bits back to the

safer and in fact it is also more simple.

David Brownell 9ebd3d822e hwmon: (lm75) add new-style driver binding
More LM75 updates:

 - Teach the LM75 driver to use new-style driver binding:

     * Create a second driver struct, using new-style driver binding
       methods cribbed from the legacy code.

     * Add a MODULE_DEVICE_TABLE (for "newER-style binding")

     * The legacy probe logic delegates its work to this new code.

     * The legacy driver now uses the name "lm75_legacy".

 - More careful initialization.  Chips are put into 9-bit mode so
   the current interconversion routines will never fail.

 - Save the original chip configuration, and restore it on exit.
   (Among other things, this normally turns off the mode where
   the chip is constantly sampling ... and thus saves power.)

So the new-style code should catch all chips that boards declare,
while the legacy code catches others.  This particular coexistence
strategy may need some work yet ... legacy modes might best be set
up explicitly by some tool not unlike "sensors-detect".  (Or else
completely eradicated...)

David Brownell 01a52397e9 hwmon: (lm75) cleanup/reorg
Minor cleanup and reorg of the lm75 code.

 - Kconfig provides a larger list of lm75-compatible chips

 - A top comment now says what the driver does (!) ... as in, just
   what sort of sensor is this??

 - Section comments now delineate the various sections of the driver:
   hwmon attributes, driver binding, register access, module glue.
   One driver binding function moved out of the attribute section,
   as did the driver struct itself.

 - Minor tweaks to legacy probe logic:  correct a comment, and
   remove a pointless variable.

 - Whitespace, linelength, and comment fixes.

This patch should include no functional changes.  It's preparation
for adding new-style (driver model) I2C driver binding.

Jean Delvare 369932f6f8 hwmon: (ad7418) Convert to a new-style i2c driver
The ad7418 driver is only used on embedded platforms where i2c
devices can easily be declared in platform code. Thus a new-style
i2c driver makes perfect sense. This lets us get rid of quirky
detection code (these chips have no identification registers) and
shrinks the binary driver size by 38%.
