This solves the dependency between lis3lv02d.[ch] and ACPI specific
methods. It introduces a ->bus_priv pointer to the device struct which is
casted to 'struct acpi_device' in the ACIP layer. Changed hp_accel.c

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.

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

hwmon subsystem. While the Philips PCF8591 device isn't a typical

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.

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.

I've voluntarily left out:
* Vendor-specific drivers: if they conflicted on any system, this would
pretty much mean that they conflict on all systems, and we would know
by now.
* 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
thermal management.
* Drivers accessing the I/O resources indirectly (e.g. through SMBus):
the checks are already done where they belong, i.e. in the bus drivers.

It turns out that we cannot create a pci_driver in this driver because PCI will
not call this module's probe function if the i5000-edac driver is already

This patch fixes the following issues in these functions:
* store: storing the result of strto[u]l in an int, resulting in a possible

* 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,

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

This driver was first written by Yan Burman. Eric Piel has updated it

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.

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.

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

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.

The thermistors use voltage channels to measure; so they don't have a
fault-alarm, but unlike the other voltages, they do have an overtemp,
which we call crit (by convention).

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

The W83781D and W83782D can be accessed either on the I2C bus or the

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.

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.

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.

In a near future, i2c_client will be allocated by i2c-core rather than

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.

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.

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...)

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.

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.

Based on earlier work by Jon Smirl and Jochen Friedrich.
This patch allows new-style i2c chip drivers to have alias names using
the official kernel aliasing system and MODULE_DEVICE_TABLE(). At this
point, the old i2c driver binding scheme (driver_name/type) is still
supported.

High-byte first is not opposite to the usual practice - that's what
almost all hardware monitoring drivers do. It is opposite to the SMBus
standard though.
Also delete a duplicate comment.

* Rework the device initialization function so as to read the
"Multi-Function Pin Control" register (0x58) once instead of twice.
I2C transactions aren't cheap so this speeds up the driver loading.
* Only create the "vrm" attribute if at least one VID value is
available.

Only request I/O ports 0x295-0x296 instead of the full I/O address
range. This solves a conflict with PNP resources on a few motherboards.
Also request the I/O ports in two parts (4 low ports, 4 high ports)
during device detection, otherwise the PNP resource makes the request
(and thus the detection) fail.

ibmpex's temperature sensors report incorrect units. Apply a conversion
factor so that tempertures report correctly. Until now, no systems seemed to
report temperatures this way, but evidently QS2x blades do.

Following patch will finally solve the detection of Intel Mobile CPUs which
share same CPUID with Desktop/Server CPUs. We need this information to test
some bit so we know if TjMax is 100C or 85C. Intel claims this works for mobiles
only, respect that and set for desktops the TjMax to 100C. Intel provided some
table on their wiki based on my chat with them at:

On my mid-2007 MacBook2, reading Ts0P sensor always failed with this message:
applesmc: wait status failed: 5 != 50.
So I assume that there's no such Ts0p sensor in this model (please confirm,
anyone). If there's the case, then we need a new set of sensors defined for
MacBook2.

Fix following warning:
WARNING: vmlinux.o(.text+0xebfd04): Section mismatch in reference from the function coretemp_cpu_callback() to the function .cpuinit.text:coretemp_device_add()
coretemp_cpu_callback() are only used inside a
HOTPLUG_CPU block so annotate it __cpuinit.
The notifier referencing the function are annotated
__refdata to silence warning from the exit function.
The unregister function do not use the embedded pointer
but clears the variable so the annotation is OK.
