2009-02-18lis3lv02d: add axes knowledge of HP Pavilion dv5 modelsGiuseppe Bilotta
Add support for HP Pavilion dv5. Since Intel-based models have an inverted x axis, while AMD-based models 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.

2009-02-18lis3lv02d: support both one- and two-byte sensorsGiuseppe Bilotta
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.

2009-02-18hp accelerometer: add freefall detectionPavel Machek
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.

However, they correspond to the same ACPI functionality, and so will always be used together, moreover as they share the same ACPI PNP alias, there is no other simple to allow to have same loaded at the same time if they are not in the same module.

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) Fix CONFIG_DMI=n fallback to probeAlistair John Strachan
When CONFIG_DMI is not enabled, dmi detection should flag that no board could be detected (err=1) rather than another error condition (err<0).

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.

2009-01-15hwmon: (k8temp) Fix temperature reporting for (most) K8 RevG CPUsAndreas Herrmann
Current Temperature for K8 RevG desktop CPUs is a "normalized value" which can be below ambient temperature. As a consequence lots of RevG systems report temperatures like: $ sensors k8temp-pci-00c3 Adapter: PCI adapter Core0 Temp: +17 C Core0 Temp: +3 C Core1 Temp: +21 C Core1 Temp: +5 C being quite below ambient temperature. There are even reports of negative temperature values. This patch corrects the temperature reporting of k8temp for RevG desktop CPUs.

The allowed combinations of processors ensure that all processors in a multisocket system have similar characteristics, e.g. (1) provide temperature sensor interface (>=RevC && <RevF) (2) are affected by erratum #141 (>=RevF) Thus it is sufficient to check the revision of the boot CPU. For "mixed silicon support" refer to "Revision Guide for AMD Athlon 64 and AMD Opteron Processors" (RevA-E) and "Revision Guide for AMD NPT Family 0Fh Processors" (RefF-G).

The sensor can be accessed via various buses. In particular, SPI, I²C and, on HP laptops, via a specific ACPI API (the only one currently supported). Separate this latest platform from the core of the sensor driver to allow support for the other bus type.
