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.

Content for the 8bit device threaded interrupt handlers. Depending on the interrupt line and chip configuration, either click or wakeup / freefall handler is called. In case of click, BTN_ event is sent via input device. In case of wakeup or freefall, input device ABS_ events are updated immediatelly. It is still possible to configure interrupt line 1 for fast freefall detection and use the second line either for click or threshold based interrupts. Or both lines can be used for click / threshold interrupts. Polled input device can be set to stopped state and still get coordinate updates via input device using interrupt based method. Polled mode and interrupt mode can also be used parallel. BTN_ events are remapped based on existing axis remapping information.

8 bit device has two wakeup / free fall units. It was not possible to configure the second unit. This patch introduces configuration entry to the platform data and also corresponding changes to the 8 bit setup function. High pass filters were enabled by default. Patch introduces configuration option for high pass filter cut off frequency and also possibility to disable or enable the filter via platform data. Since the control is a new one and default state was filter enabled, new option is used to disable the filter. This way old platform data is still compatible with the change.

Report output values as 1/1000 of earth gravity. Output values from lis3 can be read from sysfs position entry and from input device. Input device can be accessed as event device and as joystick device. Joystick device can be in two modes. Meaning of the output values varies from case to case depending on the chip type and configuration (scale). Only joystick interface in JS_CORR_BROKEN mode returned somehow similar output values in different configurations. Joystick device is in that state by default in case of lis3. Position sysfs entry, input event device and raw joystick device have been little bit broken since meaning of the output values has been varied between 12 and 8 bit devices. Applications which relayed on those methods failed if the chip is different than the expected one. This patch converts output values to mean similar thing in different configurations. Both 8 and 12 bit devices reports now same acceleration values. If somebody implements full scale support to the driver, output values will still mean the same. Scaling factor and input device range must be updated in that case. Joystick interface in JS_CORR_BROKEN mode is not touched by this patch. All other interfaces have different scale after this change. For 12 bit device scaling factor is 0.977 which keeps scaled and unscaled values are quite close to each others. For 8 bit device, scaled values are 18 times bigger than unscaled values.

Implement selftest feature as specified by chip manufacturer. Control: read selftest sysfs entry Response: "OK x y z" or "FAIL x y z" where x, y, and z are difference between selftest mode and normal mode. Test is passed when values are within acceptance limit values. Acceptance limits are provided via platform data. See chip spesifications for acceptance limits. If limits are not properly set, OK / FAIL decision is meaningless. However, userspace application can still make decision based on the numeric x, y, z values. Selftest is meant for HW diagnostic purposes. It is not meant to be called during normal use of the chip. It may cause false interrupt events. Selftest mode delays polling of the normal results but it doesn't cause wrong values. Chip must be in static state during selftest. Any acceration during the test causes most probably failure.

The LIS302DL accelerometer chip has a 'click' feature which can be used to detect sudden motion on any of the three axis. Configuration data is passed via spi platform_data and no action is taken if that's not specified, so it won't harm any existing platform. To make the configuration effective, the IRQ lines need to be set up appropriately. This patch also adds a way to do that from board support code. The DD_* definitions were factored out to an own enum because they are specific to LIS3LV02D devices.

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 ef2cfc79 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.

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.

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.
