2009-04-01lis3: solve dependency between core and ACPIDaniel Mack
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 accordingly.

2009-04-01hp_accel: axis conversion for hp compaq 8710wLuca Cappa
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.

2009-04-01hwmon: Add LTC4215 driverIra Snyder
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. :) Signed-off-by: Ira W.

2009-03-30Move the pcf8591 driver to hwmonJean Delvare
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. Signed-off-by: Jean Delvare <khali@linux-fr.org> Cc: Aurelien Jarno <aurelien@aurel32.net>

2009-03-12hwmon: (f75375s) Remove unnecessary and confusing initializationAndrew Klossner
f75375_probe calls i2c_get_clientdata to initialize the data pointer, but there isn't yet any client data to get, and the value is never used before the variable is assigned a new value seven lines later. The call doesn't hurt anything and wastes only a couple of cycles.

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.

2009-01-15hwmon: applesmc: fix light sensor readings on newer MacBooksAlex Murray
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.

2009-01-15hwmon: (abituguru3) Match partial DMI board name stringsAlistair John Strachan
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.
