2011-03-21Move hp_accel to drivers/platform/x86Jean Delvare1-405/+0
The hp_accel driver isn't a hardware monitoring driver, so it doesn't belong to drivers/hwmon. Move it to drivers/platform/x86, assuming HP doesn't ship non-x86 laptops.

2010-10-25hwmon: (lis3) add axes module parameter for custom axis-mappingTakashi Iwai1-12/+18
The axis-mapping of lis3dev device on many (rather most) HP machines doesn't follow the standard. When each new model appears, users need to adjust again. Testing this requires the rebuild of kernel, thus it's not trivial for end-users. This patch adds a module parameter "axes" to allow a custom axis-mapping without patching and recompiling the kernel driver. User can pass the parameter such as axes=3,2,1. Also it can be changed via sysfs.

2010-05-11hp_accel: fix race in device removalOliver Neukum1-1/+1
The work queue has to be flushed after the device has been made inaccessible. The patch closes a window during which a work queue might remain active after the device is removed and would then lead to ACPI calls with undefined behavior.

I have learned that the 6730b and 6730s have different accelerometer orientation, and have modified the driver accordingly (diff attached), while dropping the wild guess for AMD based 6735 having the same orientation as Intel based 6730 (this is not true for any other related series/family, thus is not probable for 673x).

2009-06-16lis3: remove automatic shutdown of the deviceEric Piel1-8/+2
After measurement on my laptop, it seems that turning off the device does not bring any energy saving (within 0.1W precision). So let's keep the device always on. It simplifies the code, and it avoids the problem of reading a wrong value sometimes just after turning the device on. Moreover, since commit ef2cfc790bf5f0ff189b01eabc0f4feb5e8524df had been too zealous, the device was actually never turned off anyway. This patch also restores the damages done by this commit concerning the initialisation/poweroff. Also do more clean up with the usage of the lis3_dev global variable.

2009-04-01hp_accel: axis conversion for hp compaq 8710wLuca Cappa1-0/+1
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 support for HP Pavilion dv5.

2009-02-18lis3lv02d: support both one- and two-byte sensorsGiuseppe Bilotta1-4/+32
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 Machek1-0/+27
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.

Move the second part of the HP laptop disk protection functionality (a red led) to the same driver. From a purely Linux developer's point of view, the led and the accelerometer have nothing related. 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.

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. The second, and more direct goal is actually to be able to merge this part with the hp-disk-leds driver, which has the same ACPI PNP number.
