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.

fe2d5ffc74 Fix platform drivers that crash on suspend/resume
It turns out that if one registers a struct platform_device, the
platform device code expects that platform_device.device->driver points
to a struct driver inside a struct platform_driver.

This is not the case with the ipmi-si, ipmi-msghandler and ibmaem
drivers, which causes the suspend/resume hook functions to jump off into
nowhere, causing a crash.  Make this assumption hold true for these
three drivers.

4777e4e6b8 hwmon: (abituguru3) Cosmetic whitespace fixes
As the probable result of zealous copy/pasting, many supported boards
contain sensor names with trailing whitespace. Though this is not a
huge problem, it is inconsistent with other sensor names, and with
other similar hwmon drivers.

Additionally, the DMI nag message added in 2.6.27 was missing a
space between two sentence fragments -- might as well clean that up
too.

Doesn't alter any kernel text, just data.

The LM99 differs from the LM86, LM89 and LM90 in that it reports

far we have been cheating and handled this in userspace but it really

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.

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

The W83781D and W83782D can be accessed either on the I2C bus or the
ISA bus. We must not access the same chip through both interfaces. So
far we were relying on the user passing the correct ignore parameter
to skip the registration of the I2C interface as suggested by
sensors-detect, but this is fragile: the user may load the w83781d
driver without running sensors-detect, and the i2c bus numbers are
not stable across reboots and hardware changes.

So, better detect alias chips in the driver directly, and skip any
I2C chip which is obviously an alias of the ISA chip. This is done
by comparing the value of 26 selected registers.

4ed1077953 hwmon: (it87) Fix thermal sensor type values
The it87 driver doesn't follow the standard sensor type values as
documented in Documentation/hwmon/sysfs-interface. It uses value 2 for
thermistors instead of value 4. This causes "sensors" to tell the user
that the chip is setup for a transistor while it is actually setup for
a thermistor.

Using value 4 for thermistors solves the problem. For compatibility
reasons, we still accept value 2 but emit a warning message so that
users update their configuration files.

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.

to cover the use cases of the legacy driver. I don't actually expect
any new-style device for that driver, but as the old i2c API is going
away soon, we have to switch to the new one.

dbc2bc251e hwmon: (dme1737) Be less i2c-centric
The dme1737 driver support both LPC (ISA) and SMBus devices. At the
moment it's rather i2c-centric, and LPC variants use a fake i2c_client
for some operations.

In a near future, i2c_client will be allocated by i2c-core rather than
by the device drivers, so non-i2c drivers will not have one. As a
preparation step, change the driver code to no longer assume that
an i2c_client structure is always available. No functional change.

bb15e7f286 ibmaem: don't query the entire sensor repository when reading energy meter
Currently, all sensors are read when the energy meter is queried via
sysfs.  This introduces a considerable amount of delay and variation in
the sysfs reading, which is not desirable when trying to profile energy
use.  Therefore, read only the energy meters when a sysfs query comes in
for them, and don't cache the results so that we always get the latest
reading.

9c5413eac5 ibmaem: prevent infinite probing loop on x3650 M2 systems
On older machines, probing for a nonexistent AEM interface returned an
IPMI error; when we saw this, we'd stop probing.  On the x3650 M2 and
(presumably) later, we are returned a value indicating success and a
buffer full of garbage or zeroes.  This causes the probe function to run
in an infinite loop.  To fix this, we add one last check--if the
interface number we're looking for is higher than the number of
interfaces that AEM claims to have, stop probing.

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.

5f44759470 hwmon: (lm85) Simplify device initialization function
Clean up and simplify the device initialization function:
* Degrade error messages to warnings - what they really are.
* Stop warning about VxI mode, we don't really care.
* Drop comment about lack of limit initialization - that's the standard
  way, all hardware monitoring drivers do that.
* Only read the configuration register once.
* Only write back to the configuration register if needed.
* Don't attempt to clear the lock bit, it locks itself to 1.
* Move the function to before it's called, so that we no longer need to
  forware declare it.

Misc cleanups to the lm85 hardware monitoring driver:
* Mark constant arrays as const.
* Remove useless masks.
* Have lm85_write_value return void - nobody is checking the returned
  value anyway and in some cases it was plain wrong.
* Remove useless initializations.
* Rename new_client to client in lm85_detect.
* Replace cascaded if/else with a switch/case in lm85_detect.
* Group similar loops in lm85_update_device.
* Remove legacy comments.

7133e56f29 hwmon: (lm85) Don't write back cached values
In set_pwm_auto_pwm_minctl, we write cached register bits back to the
chip. This is a bad idea as we have no guarantee that the cache is
up-to-date. Better read a fresh register value from the chip, it's
safer and in fact it is also more simple.

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...)

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.

b3aeab0cdb hwmon: (abituguru3) update driver detection
It has been reported that the abituguru3 driver fails to load after a BIOS
update. This patch fixes this by loosening the detection routine so that it
will work after the BIOS update too. To compensate for the now very loose
detection an additional check is added on the DMI Base Board vendor string to
make sure we only load on Abit motherboards, this is the same as the check in
the abituguru (1 / 2) driver.

d38b149794 hwmon: (lm85) Fix function RANGE_TO_REG()
Function RANGE_TO_REG() is broken. For a requested range of 2000 (2
degrees C), it will return an index value of 15, i.e. 80.0 degrees C,
instead of the expected index value of 0. All other values are handled
properly, just 2000 isn't.

The bug was introduced back in November 2004 by this patch:
http://git.kernel.org/?p=linux/kernel/git/tglx/history.git;a=commit;h=1c28d80f1992240373099d863e4996cdd5d646d0

While this can be fixed easily with the current code, I'd rather
rewrite the whole function in a way which is more obviously correct.

Based on earlier work by Jon Smirl and Jochen Friedrich.

Update most new-style i2c drivers to use standard module aliasing
instead of the old driver_name/type driver matching scheme. I've
left the video drivers apart (except for SoC camera drivers) as
they're a bit more diffcult to deal with, they'll have their own
patch later.

8f74efe81d hwmon: VRM is not written to registers
What was true of reading the VRM value is also true of writing it: not
being a register value, it doesn't need hardware access, so we don't
need a reference to the i2c client. This allows for a minor code
cleanup. As gcc appears to be smart enough to simplify the generated
code by itself, this cleanup only affects the source code, the
generated binaries are unchanged.

Also invalidate the cache instead of trying to adjust the measured fan

67b671bceb hwmon: Let the user override the detected Super-I/O device ID
While it is possible to force SMBus-based hardware monitoring chip
drivers to drive a not officially supported device, we do not have this
possibility for Super-I/O-based drivers. That's unfortunate because
sometimes newer chips are fully compatible and just forcing the driver
to load would work. Instead of that we have to tell the users to
recompile the kernel driver, which isn't an easy task for everyone.

So, I propose that we add a module parameter to all Super-I/O based
hardware monitoring drivers, letting advanced users force the driver
to load on their machine. The user has to provide the device ID of a
supposedly compatible device. This requires looking at the source code or
a datasheet, so I am confident that users can't randomly force a driver
without knowing what they are doing. Thus this should be relatively safe.

As you can see from the code, the implementation is pretty simple and
unintrusive.

87b4b6634a hwmon: (it87) request only Environment Controller ports
The IT8705F and related parts are Super I/O controllers that contain
many separate devices.

Some BIOSes describe IT8705F I/O port usage under a motherboard device
(PNP0C02) with overlapping regions, e.g., 0x290-0x29f and 0x290-0x294.

The it87 driver supports only the Environment Controller, which requires
only two ISA ports, but it used to request an eight-port range.  If that
range exceeds a range reported by the BIOS, as 0x290-0x297 would, the
request fails, and the it87 driver cannot claim the device.

This patch makes the it87 driver request only the two ports used for the
Environment Controller device.

    Gigabyte GA-K8N Ultra 9
    Gigabyte M56S-S3
    Gigabyte GA-965G-DS3

    The patch above increases the number of PNP port resources we support.
    Prior to this patch, we ignored some port resources, which masked the
    it87 problem.

The VID input level change has been reported to cause trouble. Be more
careful in this respect:
* Only change the level on the W83627EHF/EHG. The W83627DHG is more
  complex in this respect.
* Don't change the level if the VID pins are in output mode.
* Only set the level to TTL if VRM 9.x is used.

561d9a9694 HWMON: coretemp, suspend fix
It's not permitted to unregister a device after devices have been suspended.
It causes deadlocks to appear on systems with coretemp hwmon loaded.  To avoid
this, we can make coretemp_cpu_callback() do nothing if the _FROZEN bit is set
in action.
 
Also, in other cases it's generally too late to unregister the coretemp device
if the CPU is already dead, so it should be unregistered on CPU_DOWN_PREPARE.

8de577095d hwmon: (applesmc) Add support for Mac Pro 2 x Quad-Core
At least the 2x Quad-Core Apple Mac Pro appears to have some over-heat
protection which suddenly powers off the whole box under load.  This adds
support for the fans and temerature sensors in the Mac Pro - later some
"windwarm" a-like code should probably monitor the values.  For now
manually tweaking the fans prevents the sudden shutdown for me.

cd /sys/devices/platform/applesmc.768
for x in fan{1,2,3,4}; do
	echo 1 > ${x}_manual
	echo 1285 > ${x}_output
done

Two sensors are 0, while four are 129 °C, those might be removed again,
later.

df48ed804f hwmon: (w83627hf) hoist nr-1 offset out of show-store-temp-X
This hoists nr-1 offset out of (show|store)_temp_*(.*) callbacks, and into
SENSOR_DEVICE_ATTRs for sysfs tempN_X files.  It also combines
temp[1] and temp_add[2] (array) fields in w83627hf_data into 3 elem arrays,
which simplifies special-case handling of nr, allowing simplification
of callback bodies and rerolling a flattened loop in
w83627hf_update_device(struct device *dev).

The array conversion changes temp[1] from u8 to u16, but this was
happening implicitly via the helper functions anyway.
